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 */ /*! \qmltype ScatterSeries \instantiates QScatterSeries \inqmlmodule QtCharts \inherits XYSeries \brief The ScatterSeries type is used for making scatter charts.
