    \class QScatterSeries
    \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
*/

/*!
    \enum QScatterSeries::MarkerShape

    This enum describes the shape used when rendering marker items.

    \value MarkerShapeCircle
    \value MarkerShapeRectangle
*/

/*!
    \property QScatterSeries::color
    Fill (brush) color of the series. This is a convenience property for modifying the color of brush.
    \sa QScatterSeries::brush()

/*!
    \property QScatterSeries::borderColor
    Line (pen) color of the series. This is a convenience property for modifying the color of pen.

*/

/*!
  \property QScatterSeries::markerShape

  Defines the shape of the marker used to draw the points in the series. The default shape is MarkerShapeCircle.

/*!
  \property QScatterSeries::markerSize

  Defines the size of the marker used to draw the points in the series. The default size is 15.0.
