Hi,
I am wondering how to plot 2 histograms with different binning on the same canvas, there is any example code? I understand that THStack cannot handle this… One way that I can imagine by TGraph, but how to make TGraph looks like a histogram (outline)?

Thanks,
Zhiyi.

h1.Draw(); h2.Draw("same");
or make a THStack and draw it with stack.Draw(“nostack”)
