	6	The example shows how to create simple scatter chart.
	7
	8	\image scatterchart.png
	9
	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.
	11
	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.
	15
	16	\snippet ../example/scatterchart/main.cpp 2
	17
	18	In the end we create QChartView instance, set title, set anti-aliasing and add scatter series.

	20	\snippet ../example/scatterchart/main.cpp 3

	22	Chart is ready to be shown.
