/*!
    \property QXYSeries::pointLabelsFormat
    The \a format used for showing labels with series points.

    QXYSeries supports the following format tags:
    \table
      \row
        \li @xPoint      \li The x value of the data point
      \row
        \li @yPoint      \li The y value of the data point
    \endtable

    For example, the following usage of the format tags would produce labels that have the data
    point (x, y) shown inside brackets separated by a comma:
    \code
    series->setPointLabelsFormat("(@xPoint, @yPoint)");
    \endcode

    By default, the labels format is set to '@xPoint, @yPoint'. The labels are shown on the plot
    area, labels on the edge of the plot area are cut. If the points are close to each other the
    labels may overlap.
