/*! \brief This implements vertical <a href="http://en.wikipedia.org/wiki/Box_plot">boxplots</a>, optionally also a notched boxplot
    \ingroup jkqtplotter_statgraphs
 
    The x position is given in posColumn. All other data are given in the medianColumn, minColumn, maxColumn,
    percentile25Column and percentile75Column.

    The different features of a boxplot are:
 
    \image html plot_boxplotverticalelement.png
 
 
    The example \ref JKQTPlotterBoxplotStyling discusses different options to style boxplots:
 
    \image html test_styledboxplot.png
 
    This class also implements hitTest() in a way that displays all data of the boxplot in the tooltips:
 
    \image html tooltip_boxplot.png
 
    \note There are additional classes to draw a single boxplot element: JKQTPBoxplotHorizontalElement and JKQTPBoxplotVerticalElement.
          In these you can set the data values, as they are NOT drawn from a data column. This can be useful, if you e.g. want to
          draw the statistical properties of a distribution.
 
    \section BoxplotOutliers Outliers
 
    If you also want to display outliers, as shown here with circles:
 
    \image html boxplot_outliers.png
 
    You need to add them as (x,y)-pairs to the datastore and add a separate JKQTPXYLineGraph that shows these. See \ref JKQTPlotterBoxplotsGraphs for details. Here is an example code-snippet:
 
    \code
        // 4. create a graph of vertical boxplots:
        JKQTPBoxplotVerticalGraph* graph=new JKQTPBoxplotVerticalGraph(&plot);
        graph->setPositionColumn(columnPOS);
        graph->setMinColumn(columnMIN);
        graph->setPercentile25Column(columnQ25);
        graph->setMedianColumn(columnMEDIAN);
        graph->setMeanColumn(columnMEAN);
        graph->setPercentile75Column(columnQ75);
        graph->setMaxColumn(columnMAX);
        graph->setTitle("vertical Boxplots");
 
        // 5. outliers need to be drawn separately
        JKQTPXYLineGraph* graphOutliers=new JKQTPXYLineGraph(&plot);
        graphOutliers->setXColumn(columnOUTLIERSX);
        graphOutliers->setYColumn(columnOUTLIERSY);
        graphOutliers->setTitle("outliers");
        // make the color a darker shade of the color of graph
        graphOutliers->setColor(graph->getColor().darker());
        graphOutliers->setFillColor(QColor("white"));
        // draw outliers as small circles, without lines
        graphOutliers->setSymbolType(JKQTPCircle);
        graphOutliers->setDrawLine(false);
        graphOutliers->setSymbolSize(7);
    \endcode
