ROOT Graphics Drawing - THStack and axis limits

Additionally, I don’t understand the difference between SetRangeUser() and SetMaximum() or SetMinimum() . Which of these should I be using as a drawing option to set the axis range on a plot?

Here is my recipe for the x-axis:

Changing x-axis of TGraph

To go outside the existing data points (or bins), use SetLimits; to ‘zoom in’ within the limits, use SetRangeUser (for axis values) or SetRange (for bin numbers); in all cases, first you get the axis. For your example: gt->GetXaxis()->SetLimits(1, 20);

For y, SetMaximum and SetMinimum (directly on the histogram, no need to get the axis) should work.
