How to change the frame position of a histogram?

Hi rooters,

I have drawn a histogram and want to move upward the X axis,
In a Canvas, it can be done easily by dragging the axis upward.
but now i want to implement it with code.

could anyone, please, tell me how to do it?
thanks in advance,
best regards!

When you have done a change interactively, save your pad as a “.C” file (from the menu “File”) and you will see (in the generated file) what command should be used to perfom that change from code.
