Thanks for the quick response, I should have clicked the ‘Implemented in TPad’ link.
Secondly, I understand that the TAxis is not a primitive, will TVirtualPad::GetRangeAxis return the limits of the axis or the currently zoomed values as TVirtualPad::GetUxmax etc. do? Sorry the one line documentation does not always provide the most clear description.
Return pad axis coordinates range.
Is it better that I just draw the line from std::numeric_limits<double>::min() to ...max() and not worry about the axis?
