I extracted the data from all the files below. The behavior can be seen with the following code.

I attached a screenshot with the boxplot "boxplot-range" showing that the boxplot is on the frame border.

However, I am not even sure if we should change this. This is a general question if the min and max values should be at the frame border or not.

Dear PSPP team,

I tried to get a boxplot from the attached test data, but the frame of the figure overlaps with the plot. This way, it is impossible to use the plot (see test1.png).

The y axis of the boxplot should start with 0 and end with a value slightly higher than max. Ideally, the range would be an optional parameter.

A workaround is the addition of a mock variable that forces the y axis to a useful range (see workaround1.png).

Attached are the ods files for the data. Here are the scripts to reproduce the figures:

show bug:
==============================================================
pspp -O charts=bug#.png
get data /type=ods /file='BoxplotTest.ods'.
examine variables=Example /plot=boxplot .
finish.

get usable boxplot with y from 0 to 23
==============================================================
pspp -O charts=workaround#.png
get data /type=ods /file='BoxplotWorkAround.ods'.
examine variables=Example Mock /compare=variables /plot=boxplot.
finish.

Best regards, Daniel
