Hi,
I have a very basic problem. I need to superimpose a filled Graph to a histogram and then set the axis range to the min and max values in the Graph. Here is the simplified code:
TGraph *g1 = new TGraph(“file.dat”);
TGraph2D *g2D = new TGraph2D(“file2.dat”);
TH2D *h1 = g2D->GetHistogram();
h1->Draw(“col”);
g1->Draw(“F1”);
Since I draw h1 first, it fixes the axis range using h1’s bins and I can not change it to set the range to g1 min/max values. Is there a simple way to do it without having to modify my histogram (h1)?
