    \brief QtCommercial Chart series API for showing scatter series.

    Example on how to create a chart with scatter series:
    \code
    #include <qchartglobal.h>
    #include <qchartview.h>
    #include <qscatterseries.h>
    ...
    QTCOMMERCIALCHART_USE_NAMESPACE

    // Create chart widget
    QChartView *chartView = new QChartView();
    QScatterSeries *scatter = new QScatterSeries();
    *scatter << QPointF(0.5, 5.0) << QPointF(1.0, 4.5) << QPointF(1.0, 5.5) << QPointF(1.5, 5.0);
    chartView->addSeries(scatter);
    // Then add the QChartView into a layout...
    \endcode

    The example code would result the following:
