For “regular” histograms, graphs etc, I could get the axis ticks to be on both sides simply with
which is very nice. However I see that this option doesn’t apply to custom axes. I’ve tried finding something like that in the TGaxis class but saw nothing. Do you know how I can get the desired effect, preferably without cloning and resetting the values?
I’ve tried cloning too, but I didn’t find a Set/GetXmax and Y methods either.
I don’t have a simple MWE, but that’s exactly what I want. Since SetPadTickX(1) works, there has to be a way to automatically read the range of the plot and make the corresponding axis. How can I do that also for custom TGaxis? TGaxis itself doesn’t appear to provide a GetXmin etc as I mentioned.
I understand that this presupposes that the axes will be drawn in the usual places, while TGaxis is more general than this. Nevertheless I think this is a very common use case.
TGaxis is the basic low level axis painter used to draw all axis you can see in ROOT. It is a painter which draws what you tell it to draw. it does not manage th coordinates. It is up to you to tell it what to do … It won’t return you anything.
