Charts: Tick count on the Dimension Axis not working as expected

When I select the manual tick count on the Dimension Axis I would expect a behavior similar to the one I see at the KPI Axis. However it apparently does nothing.
Example: When presenting a series of dates, let’s say the daily position of a customer’s credit for a whole year, I filled in ‘12’ in the Ticks count field, expecting it to show only one tick per month, instead of on per day. But nothing happens.
Am I interpreting wrongly the way this should work?
It would also be nice that data labels would only be displayed where the ticks are shown.
Thank you,
