36 36 \brief The QAreaSeries class is used for making area charts.
37 37
38 38 \mainclass
39 39
40 40 An area chart is used to show quantitative data. It is based on line chart, in the way that area between axis and the line
41 41 is emphasized with color. Since the area chart is based on line chart, QAreaSeries constructor needs QLineSeries instance,
42 42 which defines "upper" boundary of the area. "Lower" boundary is defined by default by axis X. Instead of axis X "lower" boundary can be specified by other line.
43 43 In that case QAreaSeries should be initiated with two QLineSeries instances. Please note terms "upper" and "lower" boundary can be misleading in cases
44 44 where "lower" boundary had bigger values than the "upper" one, however the main point that area between these two boundary lines will be filled.
45 45

35 35 BarCategoriesAxis can be setup to show axis line with tick marks, grid lines and shades.
36 36 Categories are drawn between ticks. Note that you can use this also with lineseries too.
37 37 See the \l {Line and BarChart Example} {Line and BarChart Example} to learn how to do that.

42 42 \brief The Axis element is used for manipulating chart's axes.
43 43
44 44 Axis can be setup to show axis line with tick marks, grid lines and shades.
45 45 Categories are drawn between ticks. Note that you can use this also with lineseries too.
46 46
47 47 To access BarCategoriesAxis you can use ChartView API. For example:
48 48 \code
49 49 ChartView {
50 50 BarCategoriesAxis {
51 51 id: categoryAxis
52 52 categories: ["Jan", "Feb", "Mar", "Apr", "May", "Jun" ]
53 53 }
54 54 // Add a few series...
55 55 }
56 56 \endcode

38 38 \brief The Axis element is used for manipulating chart's axes
39 39
40 40 There is only one x Axis visible at the time, however there can be multiple y axes on a ChartView.
41 41 Each chart series can be bound to exactly one Y axis and the shared common X axis.
42 42 Axis can be setup to show axis line with tick marks, grid lines and shades.
43 43
44 44 To access Axes you can use ChartView API. For example:
45 45 \code
46 46 ChartView {
47 47 axisX.min: 0
48 48 axisX.max: 3
49 49 axisX.ticksCount: 4
50 50 axisY.min: 0
51 51 axisY.max: 4
52 52 // Add a few series...

37 37 \brief Series for creating a bar chart
38 38 \mainclass
39 39
40 40 QAbstractBarSeries represents a series of data shown as bars. The purpose of this class is to draw bars to
41 41 the position defined by data. Single bar is defined by QPointF, where x value is the x-coordinate of the bar
42 42 and y-value is the height of the bar. The category names are ignored with this series and x-axis
43 43 shows the x-values.
44 44
45 45 See the \l {BarChart Example} {bar chart example} to learn how to create a simple bar chart.

37 37 QStackedBarSeries represents a series of data shown as bars. The purpose of this class is to draw bars
38 38 as stacks, where bars in same category are stacked on top of each other.
39 39 QStackedBarSeries groups the data from sets to categories, which are defined by QStringList.

41 41 See the \l {StackedbarChart Example} {stacked bar chart example} to learn how to create a stacked bar chart.
