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.
