6 For example, to create a chart with line series using a widget based application:
7 \snippet ../example/chartview/main.cpp 1
8 \image chartview_example.jpg
9
10 To replace the line series with a pie series you use the dedicated QPieSeries class:
11 \snippet ../example/chartview/main.cpp 3
12 \image chartview_example_pie.jpg
13
14 To use a scatter series you use QScatterSeries class:
15 \snippet ../example/chartview/main.cpp 4
16 \image chartview_example_scatter.jpg
17
18 And to show a bar series you use one of the bar series classes, for example QBarChartSeries:
19 \snippet ../example/chartview/main.cpp 5
20 \image chartview_example_bar.jpg
21
22 If you need to give a more professional touch to your chart you can switch from the default
23 theme to one of the other themes:
24 \snippet ../example/chartview/main.cpp 2
25 \image chartview_example_theme.jpg

11 It uses Qt Graphics View Framework, therefore charts can be easily integrated 2D modern user interfaces. QCharts can be used as QWidgets, QGraphicsWidget or QML elements.
12 Users can easily create impressive graphs by selecting one of the charts themes.

22 22 \class QChartView
23 23 \brief Standalone charting widget.
24 24
25 25 QChartView is a standalone widget that can display charts. It does not require separate
26 26 QGraphicsScene to work. It manages the graphical representation of different types of
27 27 QChartSeries and other chart related objects like QChartAxis and QChartLegend. If you want to
28 28 display a chart in your existing QGraphicsScene, you can use the QChart class instead.
29 29
30 For example, to create a chart with line series using a widget based application:
31 \snippet ../example/chartview/main.cpp 1
32 \image chartview_example.jpg
33
34 Showing a few more series:
35 \snippet ../example/chartview/main.cpp 3
36 \image chartview_example_pie.jpg
37 \snippet ../example/chartview/main.cpp 4
38 \image chartview_example_scatter.jpg
39 \snippet ../example/chartview/main.cpp 5
40 \image chartview_example_bar.jpg
41
42 If you need to give a more professional touch to your chart you can switch to one of the
43 pre-defined themes:
44 \snippet ../example/chartview/main.cpp 2
45 \image chartview_example_theme.jpg
46
47 30 \sa QChart
