I have a table with grouping and on the grouping levels I want to
include a barchart visualizing the numbers.
The problem I am having is setting the maximum on the y-axis. This
should be max of the group numbers, but I can't figure out the correct
expression. If I test with a hard-coded value (corresponding to the
actual values in my test) everything is fine.
| 2 | -- |
| 4 | ---- |
| 8 | -------- |
| 4 | ---- |
Any tips?
