Non-overlapping getTitlesWidget/SideTitleWidgets

getTitlesWidget/SideTitleWidgets overlap when there are too many x-axis entries, see image.


Feature Request is to automatically call getTitlesWidget() only on x-values where it makes sense, i.e. the first x-value, the last x-value, and non-overlapping x-values in between, see second image.


Or is there currently a way to achieve this?
I created the second image by hand.

Start by locating the getTitlesWidget and SideTitleWidgets implementation and reproduce the overlap with a chart containing many x-axis entries. The work is done when labels can be selected to keep the first, last, and intermediate non-overlapping values visible, with existing behavior preserved where labels do not overlap.
