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

10 QCharts is a part of Qt Commercial addons package. It provides a set of simple chart components which are available for Qt Commercial customers.
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.
