Hello,
I would like to have a histogram containing another histogram in it, e.g. there is a histogram and there is more one which is a scaled version of the original one. Something like my attachment Pic. (see below).
Could you suggest me a possible solution in root? Thanks in advance!
see example below
Rene
void spad() {
TCanvas *c1 = new TCanvas;
TH1F *h = new TH1F("h","test",100,-3,7);
h->FillRandom("gaus",10000);
h->Draw();
TPad *smallpad = new TPad("smallpad","",0.5,0.4,0.85,0.78);
smallpad->Draw();
smallpad->cd();
TH1F *h2 = (TH1F*)h->Clone("h
2");
h2->GetXaxis()->SetRange(10,47);
h2->Draw();
c1->cd();
}
Could you give me some hint to execute this example?
I tried to run this in the following way, but I get error.
root [0] .x example_hist.C
Error: Function example_hist() is not defined in current scope :0:
*** Interpreter error recovered ***
root [1] Sorry, but I am a newbie in root.
name the script spad.C and do
root > .x spad.C
or if your file is already named example_hist.C, do
root > .L example_hist.C
root > spad()
