Different axes in boxplot diagram

[Anonymous]

Hey,

maybe someone can help me with this issue.

I want to display a boxplot diagram and additionnally the average of a value x.

Then I want to use the left axis for the boxplots and the right axis for value x.

Unfortunately the right axis is always the same as the left one no matter what definement I choose.

I use version 12.20.20200.0
