\class QBarSeries
|

\brief part of QtCommercial chart API.
|
|
|
\mainclass
|
|
|
|
|
|
QBarSeries represents a series of data shown as bars. The purpose of this class is to draw bars to
|
|
|
the position defined by data. Single bar is defined by QPointF, where x value is the x-coordinate of the bar
|
|
|
and y-value is the height of the bar. The category names are ignored with this series and x-axis
|
|
|
shows the x-values.
|
|
|
|
|
|
See the \l {BarChart Example} {bar chart example} to learn how to create a simple bar chart.

\property QBarSeries::barWidth
|
|
|
\brief The width of the bars of the series. The unit of \a width is the unit of x-axis. The minimum width for bars
|
|
|
is zero and negative values are treated as zero. Setting the width to zero means that width of the bar on screen
|
|
|
is one pixel no matter what the scale of x-axis is. Bars wider than zero are scaled with x-axis.
|
|
|
Note that with QGroupedBarSeries this value means the width of one group of bars instead of just one bar. This is
|
|
|
because with grouped series it is more logical to set width of whole group and let the chart calculate correct
|
|
|
width for bar.
