/*! \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);
|
|
