Hi Krister,
Use TH1::DrawFrame to set the range and then do not specify "A" for axis
when drawing the graph. For example in graph.C add the line begining with
TH1F and change the draw option in the line gr->Draw.
{
....
// the DrawFrame method takes the parameters (x1,y1,x2,y2).
TH1F *hr = c1->DrawFrame(0,-10,2,12);
gr = new TGraph(n,x,y);
.
// change this line and leave out the "A" for axis.
gr->Draw("CP");
.
}
Suz.
