How to get the numeric labels of a TAxis?

ROOT
1

Hello, I would like to get the numbers displayed along an axis as well as their position.
For example, on the picture below, I would like to get the {-8, -6, -4, -2, 0, 2, 4, 6, 8} of the axis on the left as well as their position

696×472

I tried to use TAxis:GetLabels but I get 0.

Thank you in advance.

GetLabels returns the alphanumeric labels if they have been set.
I am afraid that, right now, there is no way to do what you are looking for.
