Description

The BoxPlotOptions() function should be listed after the BoxPlot() function and opens up a variety of options. By using the 1st argument itemGap, the space between the individual series can be controlled. The space is entered in percent of the box width. As the default, the space equals the box width (itemGap =​ 100). For values greater than 100 (e.g. itemGap =​ 400) the boxes are narrower and the spaces between them bigger; for values less than 100 (e.g. itemGap =​ 50) the boxes are wider and the spaces smaller.

Furthermore, marker lines can be added for the arithmetic mean and median value by activating the arguments showMean = on and showMedian = on. The depiction of the mean value line is identical to the border and is controlled by the BorderStyle() function. The appearance of the median line can be controlled by the LineStyle() function.

Box plots can also be used to represent quartiles. The upper box percentile is set to equal 75% (that corresponds to the 3rd quartile) and the lower box percentile to equal 25% (that corresponds to the 1st quartile). The 2nd quartile (= 50% percentile) corresponds to the median. The quartiles are limited by the upper whisker percentile equaling 100% and by the lower whisker percentile equaling 0%.
