[ROOT] Scale axis outside the data range

Hello,

How can I set the axis range [xmin, xmax] in a graph outside the data range?
The SetRangeUser function only seems to work within the data range (e.g.
[4.0, 8.0] in the example below). If I want to fix the x-origin to "0" or
scale the x-axis to a range of e.g. [0,10] it doesn"t work.

SG

 Int_t n=5;
 Float_t x[n] = {4.0, 5.0, 6.0, 7.0, 8.0};
 Float_t y[n] = {3.0, 3.4, 4.2, 4.6, 4.8};
 TGraph *gr1 = new TGraph(n,x,y);
