\class QScatterSeries
\inmodule Qt Charts
\brief The QScatterSeries class is used for making scatter charts.
\mainclass
The scatter data is displayed as a collection of points on the chart. Each point determines the position on the horizontal axis
and the vertical axis.
\image examples_scatterchart.png
Creating basic scatter chart is simple:
\code
QScatterSeries* series = new QScatterSeries();
series->append(0, 6);
series->append(2, 4);
...
chart->addSeries(series);
\endcode
