Hi,
I have the impression that TPad::PixeltoY returns a wrong answer. Consider
the following:
root [0] TCanvas* c = new TCanvas root [1] TH2F* axes = new TH2F("","",10,-5,20,10,-1,2.5) root [2] axes->Draw() root [3] c->Draw() root [4] c->XtoPixel(5.0)
I have the impression that YtoPixel uses a positive y-axis that runs from the top to the bottom, while YtoPixel uses a positive y-axis that runs from the bottom to the top. Or am I doing something wrong?
Hajo.
