Use TPad::Range if you want to set the pad user coordinates range and want to draw yourself using the basic primitives. However it looks like you simply want to do something like in the top picture of the tutorial hbars.C it is easy to remove the drawing of the axis (x,y) with eg h->GetXaxis()->SetLabelOffset(99) and/or also setting the tick marks length to 0. If this is not what you want, please specify exactly what you try to achieve.
