How to access the (numeric) axis labels of a drawn histogram

Dear experts,

This is a bit of a strange exercise but okay. Can anyone tell me if it’s possible to access the numeric labels of a histogram, after it has been drawn in a canvas?

The default numeric labels are not stored in the flabels list. As far as I can see they are created on-the-fly when the axes are drawn. Should I be able to find them (or the axes for that matter) somewhere in a list of primitives?


Numeric labels are computing at drawing time and are not stored anywhere.
