10 To create scatter charts, QScatterSeries instance is needed. Here we create scatter series instance and we set the type, color and width of outline for scatter points.

12 \snippet ../example/scatterchart/main.cpp 1
13
14 We add data to be shown. We can use add() member function or use stream operator.

16 \snippet ../example/scatterchart/main.cpp 2

18 In the end we create QChartView instance, set title, set anti-aliasing and add scatter series.

10 10 QCharts is a part of Qt Commercial addons package. It provides a set of easy to use chart
11 11 components which are available for Qt Commercial customers. It uses Qt Graphics View
12 12 Framework, therefore charts can be easily integrated to modern 2D user interfaces. QCharts can
13 13 be used as QWidgets, QGraphicsWidget or QML elements. Users can easily create impressive
14 14 graphs by selecting one of the charts themes.
