Firstly I must appologize for what will probably be a bit of a vague question - I have only limited information at the moment.
Below is a screenshot of some output from my analysis code.
On the bottom figure you can see that I have placed a TGaxis. It is in an unusual location, however this is because I placed it so.
Of more importance is the offset of the labels. The labels intersec the axis ticks. I do not understand why this is the case, and I have not set this behaviour (to my knowledge) in my code. Hence I believe it may be a bug.
I am asking this question for another reason - I recently experienced some crashing of my drawing code. I managed to isolate the issue to be related to the plotting of this axis. At the moment I don’t know anything more than this.
It could possibly be related to this issue, but I do not know for sure.
