Labels for the x-axis of a diagram should be configurable to be shown every x th item

Think about a diagram with week entries.
So we have a coordinate value like 

"KW 01 2016"
"KW 02 2016"
etc.

One y-axis I just want to get the count

It is not possible to configre LL to use only ervy 5th or 10th label to show in the diagram axis labels.If all labels are shown it looks ugly and confusing.
Omit labels so that only every 5th ot 10th value can be shown (using a formula) would be perfect.

Currently under Axis(x)->coordinate label there is a fixed value and no way to use a formula.
