|
|
Draws a single tick label with the provided \a painter, utilizing the internal label cache to
|
|
|
5915
|
|
significantly speed up drawing of labels that were drawn in previous calls. The tick label is
|
|
|
5916
|
|
always bound to an axis, the distance to the axis is controllable via \a distanceToAxis in
|
|
|
5917
|
|
pixels. The pixel position in the axis direction is passed in the \a position parameter. Hence
|
|
|
5918
|
|
for the bottom axis, \a position would indicate the horizontal pixel position (not coordinate),
|
|
|
5919
|
|
at which the label should be drawn.
|
|
|
5920
|
|
|
|
|
5921
|
|
In order to later draw the axis label in a place that doesn't overlap with the tick labels, the
|
|
|
5922
|
|
largest tick label size is needed. This is acquired by passing a \a tickLabelsSize to the \ref
|
|
|
5923
|
|
drawTickLabel calls during the process of drawing all tick labels of one axis. In every call, \a
|
|
|
5924
|
|
tickLabelsSize is expanded, if the drawn label exceeds the value \a tickLabelsSize currently
|
|
|
5925
|
|
holds.
|
|
|
5926
|
|
|
|
|
5927
|
|
The label is drawn with the font and pen that are currently set on the \a painter. To draw
|
|
|
5928
|
|
superscripted powers, the font is temporarily made smaller by a fixed factor (see \ref
|
|
|
5929
|
|
getTickLabelData).

|
Draws a single tick label with the provided \a painter, utilizing the internal label cache to
|
|
|
|
6430
|
significantly speed up drawing of labels that were drawn in previous calls. The tick label is
|
|
|
|
6431
|
always bound to an axis, the distance to the axis is controllable via \a distanceToAxis in
|
|
|
|
6432
|
pixels. The pixel position in the axis direction is passed in the \a position parameter. Hence
|
|
|
|
6433
|
for the bottom axis, \a position would indicate the horizontal pixel position (not coordinate),
|
|
|
|
6434
|
at which the label should be drawn.
|
|
|
|
6435
|
|
|
|
|
6436
|
In order to later draw the axis label in a place that doesn't overlap with the tick labels, the
|
|
|
|
6437
|
largest tick label size is needed. This is acquired by passing a \a tickLabelsSize to the \ref
|
|
|
|
6438
|
drawTickLabel calls during the process of drawing all tick labels of one axis. In every call, \a
|
|
|
|
6439
|
tickLabelsSize is expanded, if the drawn label exceeds the value \a tickLabelsSize currently
|
|
|
|
6440
|
holds.
|
|
|
|
6441
|
|
|
|
|
6442
|
The label is drawn with the font and pen that are currently set on the \a painter. To draw
|
|
|
|
6443
|
superscripted powers, the font is temporarily made smaller by a fixed factor (see \ref
|

Every QCustomPlot owns one QCPLegend (as \a legend) by default. A legend is a small layout

8360
|
|
element inside the plot which lists the plottables with an icon of the plottable line/symbol and
|
|
|
8361
|
|
a description. The Description is retrieved from the plottable name
|
|
|
8362
|
|
(QCPAbstractPlottable::setName). Plottables can be added and removed from the legend via \ref
|
|
|
8363
|
|
QCPAbstractPlottable::addToLegend and \ref QCPAbstractPlottable::removeFromLegend. By default,
|
|
|
8364
|

QCPLegend::item, QCPLegend::itemWithPlottable, QCPLegend::addItem, QCPLegend::removeItem for

/*! \class QCPColorGradient
|
|
|
|
11189
|
\brief Defines a color gradient for use with e.g. \ref QCPColorMap
|
|
|
|
11190
|
|
|
|
|
11191
|
This class describes a color gradient which can be used to encode data with color. For example,
|
|
|
|
11192
|
QCPColorMap and QCPColorScale have a \ref QCPColorMap::setGradient "setGradient" method which
|
|
|
|
11193
|
takes an instance of this class. Colors are set with \ref setColorStopAt(double position, const QColor &color)
|
|
|
|
11194
|
with a \a position from 0 to 1. In between these defined color positions, the
|
|
|
|
11195
|
color will be interpolated linearly either in RGB or HSV space, see \ref setColorInterpolation.
|
|
|
|
11196
|
|
|
|
|
11197
|
Alternatively, load one of the preset color gradients shown in the image below, with \ref
|
|
|
|
11198
|
loadPreset, or by directly specifying the preset in the constructor.
|
|
|
|

|
\image html QCPColorGradient.png
|
|
|
|
11201
|
|
|
|
|
11202
|
The fact that the \ref QCPColorGradient(GradientPreset preset) constructor allows directly
|
|
|
|
11203
|
converting a \ref GradientPreset to a QCPColorGradient, you can also directly pass \ref
|
|
|
|
11204
|
GradientPreset to all the \a setGradient methods, e.g.:
|
|
|
|
11205
|
\code
|
|
|
|
11206
|
colorMap->setGradient(QCPColorGradient::gpHot);
|
|
|
|
11207
|
\endcode
|
|
|
|
11208
|
|
|
|
|
11209
|
The total number of levels used in the gradient can be set with \ref setLevelCount. Whether the
|
|
|
|
11210
|
color gradient shall be applied periodically (wrapping around) to data values that lie outside
|
|
|
|
11211
|
the data range specified on the plottable instance can be controlled with \ref setPeriodic.

11310
|
As shown in the image above, gradients that have the same start and end color are especially
|
|
|
|
11311
|
suitable for a periodic gradient mapping, since they produce smooth color transitions throughout
|
|

11312

the color map. A preset that has this property is \ref gpHues.
|
|
|
|
11313
|

|
|
|
11314
|
In practice, using periodic color gradients makes sense when the data corresponds to a periodic
|
|
|
|
11315
|
dimension, such as an angle or a phase. If this is not the case, the color encoding might become
|
|
|
|
11316
|
ambiguous, because multiple different data values are shown as the same color.

/*! \class QCPAxisRect
|
|
|
|
11644
|
\brief Holds multiple axes and arranges them in a rectangular shape.
|
|
|
|
11645
|
|
|
|
|
11646
|
This class represents an axis rect, a rectangular area that is bounded on all sides with an
|
|
|
|
11647
|
arbitrary number of axes.
|
|
|
|
11648
|
|
|
|
|
11649
|
Initially QCustomPlot has one axis rect, accessible via QCustomPlot::axisRect(). However, the
|
|
|
|
11650
|
layout system allows to have multiple axis rects, e.g. arranged in a grid layout
|
|
|
|
11651
|
(QCustomPlot::plotLayout).
|
|
|
|
11652
|
|
|
|
|
11653
|
By default, QCPAxisRect comes with four axes, at bottom, top, left and right. They can be
|
|
|
|
11654
|
accessed via \ref axis by providing the respective axis type (\ref QCPAxis::AxisType) and index.
|
|
|
|
11655
|
If you need all axes in the axis rect, use \ref axes. The top and right axes are set to be
|
|
|
|
11656
|
invisible initially (QCPAxis::setVisible). To add more axes to a side, use \ref addAxis or \ref
|
|
|
|
11657
|
addAxes. To remove an axis, use \ref removeAxis.
|
|
|
|
11658
|
|
|
|
|
11659
|
The axis rect layerable itself only draws a background pixmap or color, if specified (\ref
|
|
|
|
11660
|
setBackground). It is placed on the "background" layer initially (see \ref QCPLayer for an
|
|
|
|
11661
|
explanation of the QCustomPlot layer system). The axes that are held by the axis rect can be
|
|
|
|
11662
|
placed on other layers, independently of the axis rect.
|
|
|
|
11663
|
|
|
|
|
11664
|
Every axis rect has a child layout of type \ref QCPLayoutInset. It is accessible via \ref
|
|
|
|
11665
|
insetLayout and can be used to have other layout elements (or even other layouts with multiple
|
|
|
|
11666
|
elements) hovering inside the axis rect.
|
|
|
|
11667
|
|
|
|
|
11668
|
If an axis rect is clicked and dragged, it processes this by moving certain axis ranges. The
|
|
|
|
11669
|
behaviour can be controlled with \ref setRangeDrag and \ref setRangeDragAxes. If the mouse wheel
|
|
|
|
11670
|
is scrolled while the cursor is on the axis rect, certain axes are scaled. This is controllable
|
|
|
|
11671
|
via \ref setRangeZoom, \ref setRangeZoomAxes and \ref setRangeZoomFactor. These interactions are
|
|
|
|
11672
|
only enabled if \ref QCustomPlot::setInteractions contains \ref QCP::iRangeDrag and \ref
|
|
|
|
11673
|
QCP::iRangeZoom.

Event handler for mouse wheel events. If rangeZoom is Qt::Horizontal, Qt::Vertical or both, the
|
|
|
|
12578
|
ranges of the axes defined as rangeZoomHorzAxis and rangeZoomVertAxis are scaled. The center of
|
|
|
|
12579
|
the scaling operation is the current cursor position inside the axis rect. The scaling factor is
|
|
|
|
12580
|
dependant on the mouse wheel delta (which direction the wheel was rotated) to provide a natural
|
|
|
|
12581
|
zooming feel. The Strength of the zoom can be controlled via \ref setRangeZoomFactor.
|
|
|
|
12582
|
|
|
|
|
12583
|
Note, that event->delta() is usually +/-120 for single rotation steps. However, if the mouse
|
|
|
|
12584
|
wheel is turned rapidly, many steps may bunch up to one event, so the event->delta() may then be
|
|
|
|
12585
|
multiples of 120. This is taken into account here, by calculating \a wheelSteps and using it as
|
|
|
|
12586
|
exponent of the range zoom factor. This takes care of the wheel direction automatically, by
|
|
|
|
12587
|
inverting the factor, when the wheel step is negative (f^-1 = 1/f).

/*! \class QCPAbstractLegendItem
|
|
|
|
12621
|
\brief The abstract base class for all entries in a QCPLegend.
|
|
|
|
12622
|
|
|
|
|
12623
|
It defines a very basic interface for entries in a QCPLegend. For representing plottables in the
|
|
|
|
12624
|
legend, the subclass \ref QCPPlottableLegendItem is more suitable.
|
|
|
|
12625
|
|
|
|
|
12626
|
Only derive directly from this class when you need absolute freedom (e.g. a custom legend entry
|
|
|
|
12627
|
that's not even associated with a plottable).
|
|
|
|
12628
|
|
|
|
|
12629
|
You must implement the following pure virtual functions:
|
|
|
|
12630
|
\li \ref draw (from QCPLayerable)
|
|
|
|
12631
|
|
|
|
|
12632
|
You inherit the following members you may use:
|
|
|
|
12633
|
<table>
|
|
|
|
12634
|
<tr>
|
|
|
|
12635
|
<td>QCPLegend *\b mParentLegend</td>
|
|
|
|
12636
|
<td>A pointer to the parent QCPLegend.</td>
|
|
|
|
12637
|
</tr><tr>
|
|
|
|
12638
|
<td>QFont \b mFont</td>
|
|
|
|
12639
|
<td>The generic font of the item. You should use this font for all or at least the most prominent text of the item.</td>
|
|
|
|
12640
|
</tr>
|
|
|
|
12641
|
</table>
|
|
|
|

12802
|
\brief A legend item representing a plottable with an icon and the plottable name.
|
|
|
|
12803
|
|
|
|
|
12804
|
This is the standard legend item for plottables. It displays an icon of the plottable next to the
|
|
|
|
12805
|
plottable name. The icon is drawn by the respective plottable itself (\ref
|
|
|
|
12806
|
QCPAbstractPlottable::drawLegendIcon), and tries to give an intuitive symbol for the plottable.
|
|
|
|
12807
|
For example, the QCPGraph draws a centered horizontal line and/or a single scatter point in the
|
|
|
|
12808
|
middle.
|
|
|
|
12809
|
|
|
|
|
12810
|
Legend items of this type are always associated with one plottable (retrievable via the
|
|
|
|
12811
|
plottable() function and settable with the constructor). You may change the font of the plottable
|
|
|
|
12812
|
name with \ref setFont. Icon padding and border pen is taken from the parent QCPLegend, see \ref
|
|
|
|
12813
|
QCPLegend::setIconBorderPen and \ref QCPLegend::setIconTextPadding.
|
|
|
|
12814
|
|
|
|
|
12815
|
The function \ref QCPAbstractPlottable::addToLegend/\ref QCPAbstractPlottable::removeFromLegend
|
|
|
|
12816
|
creates/removes legend items of this type in the default implementation. However, these functions
|
|
|
|
12817
|
may be reimplemented such that a different kind of legend item (e.g a direct subclass of
|
|
|
|
12818
|
QCPAbstractLegendItem) is used for that plottable.
|
|
|
|
12819
|
|
|
|
|
12820
|
Since QCPLegend is based on QCPLayoutGrid, a legend item itself is just a subclass of
|
|
|
|
12821
|
QCPLayoutElement. While it could be added to a legend (or any other layout) via the normal layout
|
|
|
|
12822
|
interface, QCPLegend has specialized functions for handling legend items conveniently, see the
|
|
|
|
12823
|
documentation of \ref QCPLegend.

|
\brief Manages a legend inside a QCustomPlot.
|
|
|
|
12925
|
|
|
|
|
12926
|
A legend is a small box somewhere in the plot which lists plottables with their name and icon.
|
|
|
|
12927
|
|
|
|
|
12928
|
Normally, the legend is populated by calling \ref QCPAbstractPlottable::addToLegend. The
|
|
|
|
12929
|
respective legend item can be removed with \ref QCPAbstractPlottable::removeFromLegend. However,
|
|
|
|
12930
|
QCPLegend also offers an interface to add and manipulate legend items directly: \ref item, \ref
|
|
|
|
12931
|
itemWithPlottable, \ref itemCount, \ref addItem, \ref removeItem, etc.
|
|
|
|
12932
|
|
|
|
|
12933
|
The QCPLegend derives from QCPLayoutGrid and as such can be placed in any position a
|
|
|
|
12934
|
QCPLayoutElement may be positioned. The legend items are themselves QCPLayoutElements which are
|
|
|
|
12935
|
placed in the grid layout of the legend. QCPLegend only adds an interface specialized for
|
|
|
|
12936
|
handling child elements of type QCPAbstractLegendItem, as mentioned above. In principle, any
|
|
|
|
12937
|
other layout elements may also be added to a legend via the normal \ref QCPLayoutGrid interface.
|
|
|
|
12938
|
However, the QCPAbstractLegendItem-Interface will ignore those elements (e.g. \ref itemCount will
|
|
|
|
12939
|
only return the number of items with QCPAbstractLegendItems type).
|
|
|
|
12940
|
|
|
|
|
12941
|
By default, every QCustomPlot has one legend (QCustomPlot::legend) which is placed in the inset
|
|
|
|
12942
|
layout of the main axis rect (\ref QCPAxisRect::insetLayout). To move the legend to another
|
|
|
|
12943
|
position inside the axis rect, use the methods of the \ref QCPLayoutInset. To move the legend
|
|
|
|
12944
|
outside of the axis rect, place it anywhere else with the QCPLayout/QCPLayoutElement interface.

|
\brief A layout element displaying a plot title text
|
|
|
|
13494
|
|
|
|
|
13495
|
The text may be specified with \ref setText, theformatting can be controlled with \ref setFont
|
|
|
|
13496
|
and \ref setTextColor.
|
|
|
|
13497
|
|
|
|
|
13498
|
A plot title can be added as follows:
|
|
|
|
13499
|
\code
|
|
|
|
13500
|
customPlot->plotLayout()->insertRow(0); // inserts an empty row above the default axis rect
|
|
|
|
13501
|
customPlot->plotLayout()->addElement(0, 0, new QCPPlotTitle(customPlot, "Your Plot Title"));
|
|
|
|
13502
|
\endcode
|
|
|
|
13503
|
|
|
|
|
13504
|
Since a plot title is a common requirement, QCustomPlot offers specialized selection signals for
|
|
|
|
13505
|
easy interaction with QCPPlotTitle. If a layout element of type QCPPlotTitle is clicked, the
|
|
|
|
13506
|
signal \ref QCustomPlot::titleClick is emitted. A double click emits the \ref
|
|
|
|
13507
|
QCustomPlot::titleDoubleClick signal.

|
|

|

|

13743
|
\brief A color scale for use with color coding data such as QCPColorMap
|
|
|
|
13744
|
|
|
|
|
13745
|
This layout element can be placed on the plot to correlate a color gradient with data values. It
|
|
|
|
13746
|
is usually used in combination with one or multiple \ref QCPColorMap "QCPColorMaps".
|
|
|
|
13747
|
|
|
|
|
13748
|
\image html QCPColorScale.png
|
|
|
|
13749
|
|
|
|
|
13750
|
The color scale can be either horizontal or vertical, as shown in the image above. The
|
|
|
|
13751
|
orientation and the side where the numbers appear is controlled with \ref setType.
|
|
|
|
13752
|
|
|
|
|
13753
|
Use \ref QCPColorMap::setColorScale to connect a color map with a color scale. Once they are
|
|
|
|
13754
|
connected, they share their gradient, data range and data scale type (\ref setGradient, \ref
|
|
|
|
13755
|
setDataRange, \ref setDataScaleType). Multiple color maps may be associated with a single color
|
|
|
|
13756
|
scale, to make them all synchronize these properties.
|
|
|
|
13757
|
|
|
|
|
13758
|
To have finer control over the number display and axis behaviour, you can directly access the
|
|
|
|
13759
|
\ref axis. See the documentation of QCPAxis for details about configuring axes. For example, if
|
|
|
|
13760
|
you want to change the number of automatically generated ticks, call
|
|
|
|
13761
|
\code
|
|
|
|
13762
|
colorScale->axis()->setAutoTickCount(3);
|
|
|
|
13763
|
\endcode
|
|
|
|
13764
|
|
|
|
|
13765
|
Placing a color scale next to the main axis rect works like with any other layout element:
|
|
|
|
13766
|
\code
|
|
|
|
13767
|
QCPColorScale *colorScale = new QCPColorScale(customPlot);
|
|
|
|
13768
|
customPlot->plotLayout()->addElement(0, 1, colorScale);
|
|
|
|
13769
|
colorScale->setLabel("Some Label Text");
|
|
|
|
13770
|
\endcode
|
|
|
|
13771
|
In this case we have placed it to the right of the default axis rect, so it wasn't necessary to
|
|
|
|
13772
|
call \ref setType, since \ref QCPAxis::atRight is already the default. The text next to the color
|
|
|
|
13773
|
scale can be set with \ref setLabel.
|
|
|
|
13774
|
|
|
|
|
13775
|
For optimum appearance (like in the image above), it may be desirable to line up the axis rect and
|
|
|
|
13776
|
the borders of the color scale. Use a \ref QCPMarginGroup to achieve this:
|
|
|
|
13777
|
\code
|
|
|
|
13778
|
QCPMarginGroup *group = new QCPMarginGroup(customPlot);
|
|
|
|
13779
|
colorScale->setMarginGroup(QCP::msTop|QCP::msBottom, group);
|
|
|
|
13780
|
customPlot->axisRect()->setMarginGroup(QCP::msTop|QCP::msBottom, group);
|
|
|
|
13781
|
\endcode
|
|
|
|
13782
|
|
|
|
|
13783
|
Color scales are initialized with a non-zero minimum top and bottom margin (\ref
|
|
|
|
13784
|
setMinimumMargins), because vertical color scales are most common and the minimum top/bottom
|
|
|
|
13785
|
margin makes sure it keeps some distance to the top/bottom widget border. So if you change to a
|
|
|
|
13786
|
horizontal color scale by setting \ref setType to \ref QCPAxis::atBottom or \ref QCPAxis::atTop, you
|
|
|
|
13787
|
might want to also change the minimum margins accordingly, e.g. \ref
|
|
|
|
13788
|
setMinimumMargins(QMargins(6, 0, 6, 0)).
|
|
|

Sets whether adaptive sampling shall be used when plotting this graph. QCustomPlot's adaptive

|
sampling technique can drastically improve the replot performance for graphs with a larger number
|
|
|

14833

|

14834

By default, adaptive sampling is enabled. Even if enabled, QCustomPlot decides whether adaptive
|
|
|
|
14836
|
sampling shall actually be used on a per-graph basis. So leaving adaptive sampling enabled has no
|
|
|
|
14837

disadvantage in almost all cases.

As can be seen, line plots experience no visual degradation from adaptive sampling. Outliers are
|
|
|
|
14842
|
reproduced reliably, as well as the overall shape of the data set. The replot time reduces
|
|
|
|
14843
|
dramatically though. This allows QCustomPlot to display large amounts of data in realtime.

14847
|
Care must be taken when using high-density scatter plots in combination with adaptive sampling.
|
|
|
|
14848
|
The adaptive sampling algorithm treats scatter plots more carefully than line plots which still
|
|
|
|
14849
|
gives a significant reduction of replot times, but not quite as much as for line plots. This is
|
|
|
|
14850
|
because scatter plots inherently need more data points to be preserved in order to still resemble
|
|
|
|
14851
|
the original, non-adaptive-sampling plot. As shown above, the results still aren't quite
|
|
|
|
14852
|
identical, as banding occurs for the outer data points. This is in fact intentional, such that
|
|
|
|
14853
|
the boundaries of the data cloud stay visible to the viewer. How strong the banding appears,
|
|
|
|
14854
|
depends on the point density, i.e. the number of points in the plot.

General idea: If the two points of a line segment are in the same region (that is not R), the line segment corner is removed.

Curves outside R become straight lines closely outside of R which greatly reduces drawing time, yet keeps the look of lines and

/*! \class QCPColorMapData
|
|
|
|
18418
|
\brief Holds the two-dimensional data of a QCPColorMap plottable.
|
|
|
|
18419
|
|
|
|
|
18420
|
This class is a data storage for \ref QCPColorMap. It holds a two-dimensional array, which \ref
|
|
|
|
18421
|
QCPColorMap then displays as a 2D image in the plot, where the array values are represented by a
|
|
|
|
18422
|
color, depending on the value.
|
|
|
|
18423
|
|
|
|
|
18424
|
The size of the array can be controlled via \ref setSize (or \ref setKeySize, \ref setValueSize).
|
|
|
|
18425
|
Which plot coordinates these cells correspond to can be configured with \ref setRange (or \ref
|
|
|
|
18426
|
setKeyRange, \ref setValueRange).
|
|
|
|
18427
|
|
|
|
|
18428
|
The data cells can be accessed in two ways: They can be directly addressed by an integer index
|
|
|
|
18429
|
with \ref setCell. This is the fastest method. Alternatively, they can be addressed by their plot
|
|
|
|
18430
|
coordinate with \ref setData. plot coordinate to cell index transformations and vice versa are
|
|
|
|
18431
|
provided by the functions \ref coordToCell and \ref cellToCoord.
|
|
|
|
18432
|
|
|
|
|
18433
|
This class also buffers the minimum and maximum values that are in the data set, to provide
|
|
|
|
18434
|
QCPColorMap::rescaleDataRange with the necessary information quickly. Setting a cell to a value
|
|
|
|
18435
|
that is greater than the current maximum increases this maximum to the new value. However,
|
|
|
|
18436
|
setting the cell that currently holds the maximum value to a smaller value doesn't decrease the
|
|
|
|
18437
|
maximum again, because finding the true new maximum would require going through the entire data
|
|
|
|
18438
|
array, which might be time consuming. The same holds for the data minimum. This functionality is
|
|
|
|
18439
|
given by \ref recalculateDataBounds, such that you can decide when it is sensible to find the
|
|
|
|
18440
|
true current minimum and maximum. The method QCPColorMap::rescaleDataRange offers a convenience
|
|
|
|
18441
|
parameter \a recalculateDataBounds which may be set to true to automatically call \ref
|
|
|
|
18442
|
recalculateDataBounds internally.

\brief A plottable representing a two-dimensional color map in a plot.

The data is stored in the class \ref QCPColorMapData, which can be accessed via the data()
|
|
|
|
18796
|
method.
|
|
|
|
18797
|
|
|
|
|
18798
|
A color map has three dimensions to represent a data point: The \a key dimension, the \a value
|
|
|
|
18799
|
dimension and the \a data dimension. As with other plottables such as graphs, \a key and \a value
|
|
|
|
18800
|
correspond to two orthogonal axes on the QCustomPlot surface that you specify in the QColorMap
|
|
|
|
18801
|
constructor. The \a data dimension however is encoded as the color of the point at (\a key, \a
|
|
|
|
18802
|
value).
|
|
|
|
18803
|
|
|
|
|
18804
|
Set the number of points (or \a cells) in the key/value dimension via \ref
|
|
|
|
18805
|
QCPColorMapData::setSize. The plot coordinate range over which these points will be displayed is
|
|
|
|
18806
|
specified via \ref QCPColorMapData::setRange. The first cell will be centered on the lower range
|
|
|
|
18807
|
boundary and the last cell will be centered on the upper range boundary. The data can be set by
|
|
|
|
18808
|
either accessing the cells directly with QCPColorMapData::setCell or by addressing the cells via
|
|
|
|
18809
|
their plot coordinates with \ref QCPColorMapData::setData. If possible, you should prefer
|
|

To show the user which colors correspond to which \a data values, a \ref QCPColorScale is
|
|
|
|
18817
|
typically placed to the right of the axis rect. See the documentation there for details on how to

add and use a color scale.

\section appearance Changing the appearance
|
|
|
|
18821
|
|
|
|
|
18822
|
The central part of the appearance is the color gradient, which can be specified via \ref
|
|
|
|
18823
|
setGradient. See the documentation of \ref QCPColorGradient for details on configuring a color
|
|

|
18824
|
gradient.
|
|
|
|
18825
|
|
|
|
|
18826
|
The \a data range that is mapped to the colors of the gradient can be specified with \ref
|
|
|
|
18827
|
setDataRange. To make the data range encompass the whole data set minimum to maximum, call \ref
|
|
|
|
18828
|
rescaleDataRange.

\section usage Usage

|
|
18831

18832
|
Like all data representing objects in QCustomPlot, the QCPColorMap is a plottable
|
|
|
|
18833
|
(QCPAbstractPlottable). So the plottable-interface of QCustomPlot applies
|
|
|
|
18834
|
(QCustomPlot::plottable, QCustomPlot::addPlottable, QCustomPlot::removePlottable, etc.)
|
|
|
|
18835
|
|
|
|
|
18836
|
Usually, you first create an instance:
|
|
|
|
18837
|
\code
|
|
|
|
18838
|
QCPColorMap *colorMap = new QCPColorMap(customPlot->xAxis, customPlot->yAxis);\endcode
|
|
|
|
18839
|
add it to the customPlot with QCustomPlot::addPlottable:
|
|
|
|
18840
|
\code
|
|
|
|
18841
|
customPlot->addPlottable(colorMap);\endcode
|
|
|
|
18842
|
and then modify the properties of the newly created color map, e.g.:
|
|
|
|
18843
|
\code
|
|
|
|
18844
|
colorMap->data()->setSize(50, 50);
|
|
|
|
18845
|
colorMap->data()->setRange(QCPRange(0, 2), QCPRange(0, 2));
|
|
|
|
18846
|
for (int x=0; x<50; ++x)
|
|
|
|
18847
|
for (int y=0; y<50; ++y)
|
|
|
|
18848
|
colorMap->data()->setCell(x, y, qCos(x/10.0)+qSin(y/10.0));
|
|
|
|
18849
|
colorMap->setGradient(QCPColorGradient::gpPolar);
|
|
|
|
18850
|
colorMap->rescaleDataRange(true);
|
|
|
|
18851
|
customPlot->rescaleAxes();
|
|
|
|
18852
|
customPlot->replot();
|
|
|
|
18853
|
\endcode
|
|
|
|
18854
|
|
|
|
|
18855
|
\note The QCPColorMap always displays the data at equal key/value intervals, even if the key or
|
|
|
|
18856
|
value axis is set to a logarithmic scaling. If you want to use QCPColorMap with logarithmic axes,
|
|
|
|
18857
|
you shouldn't use the \ref QCPColorMapData::setData method as it uses a linear transformation to
|
|
|
|
18858
|
determine the cell index. Rather directly access the cell index with \ref
|
|
|
|
18859
|
QCPColorMapData::setCell.

Sets the data range (\ref setDataRange) to span the minimum and maximum values that occur in the
|
|
|
|
19069
|
current data set. This corresponds to the \ref rescaleKeyAxis or \ref rescaleValueAxis methods,
|
|
|
|
19070
|
only for the third data dimension of the color map.
|
|
|
|
19071
|
|
|
|
|
19072
|
The minimum and maximum values of the data set are buffered in the internal QCPColorMapData
|
|
|
|
19073
|
instance (\ref data). As data is updated via its \ref QCPColorMapData::setCell or \ref
|
|
|
|
19074
|
QCPColorMapData::setData, the buffered minimum and maximum values are updated, too. For
|
|
|
|
19075
|
performance reasons, however, they are only updated in an expanding fashion. So the buffered
|
|
|
|
19076
|
maximum can only increase and the buffered minimum can only decrease. In consequence, changes to
|
|
|
|
19077
|
the data that actually lower the maximum of the data set (by overwriting the cell holding the
|
|
|
|
19078
|
current maximum with a smaller value), aren't recognized and the buffered maximum overestimates
|
|
|
|
19079
|
the true maximum of the data set. The same happens for the buffered minimum. To recalculate the
|
|
|
|
19080
|
true minimum and maximum by explicitly looking at each cell, the method
|
|
|
|
19081
|
QCPColorMapData::recalculateDataBounds can be used. For convenience, setting the parameter \a
|
|
|
|
19082
|
recalculateDataBounds calls this method before setting the data range to the buffered minimum and
|
|
|
|
19083
|
maximum.

/*! \class QCPAxisRect
|
|
|
16886
|
|
\brief Holds multiple axes and arranges them in a rectangular shape.
|
|
|
16887
|
|
|
|
|
16888
|
|
This class represents an axis rect, a rectangular area that is bounded on all sides with an
|
|
|
16889
|
|
arbitrary number of axes.
|
|
|
16890
|
|
|
|
|
16891
|
|
Initially QCustomPlot has one axis rect, accessible via QCustomPlot::axisRect(). However, the
|
|
|
16892
|
|
layout system allows to have multiple axis rects, e.g. arranged in a grid layout
|
|
|
16893
|
|
(QCustomPlot::plotLayout).
|
|
|
16894
|
|
|
|
|
16895
|
|
By default, QCPAxisRect comes with four axes, at bottom, top, left and right. They can be
|
|
|
16896
|
|
accessed via \ref axis by providing the respective axis type (\ref QCPAxis::AxisType) and index.
|
|
|
16897
|
|
If you need all axes in the axis rect, use \ref axes. The top and right axes are set to be
|
|
|
16898
|
|
invisible initially (QCPAxis::setVisible). To add more axes to a side, use \ref addAxis or \ref
|
|
|
16899
|
|
addAxes. To remove an axis, use \ref removeAxis.
|
|
|
16900
|
|
|
|
|
16901
|
|
The axis rect layerable itself only draws a background pixmap or color, if specified (\ref
|
|
|
16902
|
|
setBackground). It is placed on the "background" layer initially (see \ref QCPLayer for an
|
|
|
16903
|
|
explanation of the QCustomPlot layer system). The axes that are held by the axis rect can be
|
|
|
16904
|
|
placed on other layers, independently of the axis rect.
|
|
|
16905
|
|
|
|
|
16906
|
|
Every axis rect has a child layout of type \ref QCPLayoutInset. It is accessible via \ref
|
|
|
16907
|
|
insetLayout and can be used to have other layout elements (or even other layouts with multiple
|
|
|
16908
|
|
elements) hovering inside the axis rect.
|
|
|
16909
|
|
|
|
|
16910
|
|
If an axis rect is clicked and dragged, it processes this by moving certain axis ranges. The
|
|
|
16911
|
|
behaviour can be controlled with \ref setRangeDrag and \ref setRangeDragAxes. If the mouse wheel
|
|
|
16912
|
|
is scrolled while the cursor is on the axis rect, certain axes are scaled. This is controllable
|
|
|
16913
|
|
via \ref setRangeZoom, \ref setRangeZoomAxes and \ref setRangeZoomFactor. These interactions are
|
|
|
16914
|
|
only enabled if \ref QCustomPlot::setInteractions contains \ref QCP::iRangeDrag and \ref
|
|
|
16915
|
|
QCP::iRangeZoom.

Event handler for mouse wheel events. If rangeZoom is Qt::Horizontal, Qt::Vertical or both, the
|
|
|
17791
|
|
ranges of the axes defined as rangeZoomHorzAxis and rangeZoomVertAxis are scaled. The center of
|
|
|
17792
|
|
the scaling operation is the current cursor position inside the axis rect. The scaling factor is
|
|
|
17793
|
|
dependant on the mouse wheel delta (which direction the wheel was rotated) to provide a natural
|
|
|
17794
|
|
zooming feel. The Strength of the zoom can be controlled via \ref setRangeZoomFactor.
|
|
|
17795
|
|
|
|
|
17796
|
|
Note, that event->delta() is usually +/-120 for single rotation steps. However, if the mouse
|
|
|
17797
|
|
wheel is turned rapidly, many steps may bunch up to one event, so the event->delta() may then be
|
|
|
17798
|
|
multiples of 120. This is taken into account here, by calculating \a wheelSteps and using it as
|
|
|
17799
|
|
exponent of the range zoom factor. This takes care of the wheel direction automatically, by
|
|
|
17800
|
|
inverting the factor, when the wheel step is negative (f^-1 = 1/f).

/*! \class QCPAbstractLegendItem
|
|
|
17834
|
|
\brief The abstract base class for all entries in a QCPLegend.
|
|
|
17835
|
|
|
|
|
17836
|
|
It defines a very basic interface for entries in a QCPLegend. For representing plottables in the
|
|
|
17837
|
|
legend, the subclass \ref QCPPlottableLegendItem is more suitable.
|
|
|
17838
|
|
|
|
|
17839
|
|
Only derive directly from this class when you need absolute freedom (e.g. a custom legend entry
|
|
|
17840
|
|
that's not even associated with a plottable).
|
|
|
17841
|
|
|
|
|
17842
|
|
You must implement the following pure virtual functions:
|
|
|
17843
|
|
\li \ref draw (from QCPLayerable)
|
|
|
17844
|
|
|
|
|
17845
|
|
You inherit the following members you may use:
|
|
|
17846
|
|
<table>
|
|
|
17847
|
|
<tr>
|
|
|
17848
|
|
<td>QCPLegend *\b mParentLegend</td>
|
|
|
17849
|
|
<td>A pointer to the parent QCPLegend.</td>
|
|
|
17850
|
|
</tr><tr>
|
|
|
17851
|
|
<td>QFont \b mFont</td>
|
|
|
17852
|
|
<td>The generic font of the item. You should use this font for all or at least the most prominent text of the item.</td>
|
|
|
17853
|
|
</tr>
|
|
|
17854
|
|
</table>

|
|
\brief A legend item representing a plottable with an icon and the plottable name.
|
|
|
18012
|
|
|
|
|
18013
|
|
This is the standard legend item for plottables. It displays an icon of the plottable next to the
|
|
|
18014
|
|
plottable name. The icon is drawn by the respective plottable itself (\ref
|
|
|
18015
|
|
QCPAbstractPlottable::drawLegendIcon), and tries to give an intuitive symbol for the plottable.
|
|
|
18016
|
|
For example, the QCPGraph draws a centered horizontal line and/or a single scatter point in the
|
|
|
18017
|
|
middle.
|
|
|
18018
|
|
|
|
|
18019
|
|
Legend items of this type are always associated with one plottable (retrievable via the
|
|
|
18020
|
|
plottable() function and settable with the constructor). You may change the font of the plottable
|
|
|
18021
|
|
name with \ref setFont. Icon padding and border pen is taken from the parent QCPLegend, see \ref
|
|
|
18022
|
|
QCPLegend::setIconBorderPen and \ref QCPLegend::setIconTextPadding.
|
|
|
18023
|
|
|
|
|
18024
|
|
The function \ref QCPAbstractPlottable::addToLegend/\ref QCPAbstractPlottable::removeFromLegend
|
|
|
18025
|
|
creates/removes legend items of this type in the default implementation. However, these functions
|
|
|
18026
|
|
may be reimplemented such that a different kind of legend item (e.g a direct subclass of
|
|
|
18027
|
|
QCPAbstractLegendItem) is used for that plottable.
|
|
|
18028
|
|
|
|
|
18029
|
|
Since QCPLegend is based on QCPLayoutGrid, a legend item itself is just a subclass of
|
|
|
18030
|
|
QCPLayoutElement. While it could be added to a legend (or any other layout) via the normal layout
|
|
|
18031
|
|
interface, QCPLegend has specialized functions for handling legend items conveniently, see the
|
|
|
18032
|
|
documentation of \ref QCPLegend.

|
\brief Manages a legend inside a QCustomPlot.
|
|
|
18134
|
|
|
|
|
18135
|
|
A legend is a small box somewhere in the plot which lists plottables with their name and icon.
|
|
|
18136
|
|
|
|
|
18137
|
|
Normally, the legend is populated by calling \ref QCPAbstractPlottable::addToLegend. The
|
|
|
18138
|
|
respective legend item can be removed with \ref QCPAbstractPlottable::removeFromLegend. However,
|
|
|
18139
|
|
QCPLegend also offers an interface to add and manipulate legend items directly: \ref item, \ref
|
|
|
18140
|
|
itemWithPlottable, \ref itemCount, \ref addItem, \ref removeItem, etc.
|
|
|
18141
|
|
|
|
|
18142
|
|
The QCPLegend derives from QCPLayoutGrid and as such can be placed in any position a
|
|
|
18143
|
|
QCPLayoutElement may be positioned. The legend items are themselves QCPLayoutElements which are
|
|
|
18144
|
|
placed in the grid layout of the legend. QCPLegend only adds an interface specialized for
|
|
|
18145
|
|
handling child elements of type QCPAbstractLegendItem, as mentioned above. In principle, any
|
|
|
18146
|
|
other layout elements may also be added to a legend via the normal \ref QCPLayoutGrid interface.
|
|
|
18147
|
|
However, the QCPAbstractLegendItem-Interface will ignore those elements (e.g. \ref itemCount will
|
|
|
18148
|
|
only return the number of items with QCPAbstractLegendItems type).
|
|
|
18149
|
|
|
|
|
18150
|
|
By default, every QCustomPlot has one legend (QCustomPlot::legend) which is placed in the inset
|
|
|
18151
|
|
layout of the main axis rect (\ref QCPAxisRect::insetLayout). To move the legend to another
|
|
|
18152
|
|
position inside the axis rect, use the methods of the \ref QCPLayoutInset. To move the legend
|
|
|
18153
|
|
outside of the axis rect, place it anywhere else with the QCPLayout/QCPLayoutElement interface.

|
|
\brief A layout element displaying a plot title text
|
|
|
18699
|
|
|
|
|
18700
|
|
The text may be specified with \ref setText, theformatting can be controlled with \ref setFont
|
|
|
18701
|
|
and \ref setTextColor.
|
|
|
18702
|
|
|
|
|
18703
|
|
A plot title can be added as follows:
|
|
|
18704
|
|
\code
|
|
|
18705
|
|
customPlot->plotLayout()->insertRow(0); // inserts an empty row above the default axis rect
|
|
|
18706
|
|
customPlot->plotLayout()->addElement(0, 0, new QCPPlotTitle(customPlot, "Your Plot Title"));
|
|
|
18707
|
|
\endcode
|
|
|
18708
|
|
|
|
|
18709
|
|
Since a plot title is a common requirement, QCustomPlot offers specialized selection signals for
|
|
|
18710
|
|
easy interaction with QCPPlotTitle. If a layout element of type QCPPlotTitle is clicked, the
|
|
|
18711
|
|
signal \ref QCustomPlot::titleClick is emitted. A double click emits the \ref
|
|
|
18712
|
|
QCustomPlot::titleDoubleClick signal.

|
