Hello,
I would like to use the widget that appear when I call Add, Divide or Multiply from the context menu of a histogram, but I’m not able to understand what I have to insert into the box that should contains the histogram pointers.
For example, I have created two histogram in two different canvases
TH1D * h1 = new TH1D(“h”, “h”, 100, 0, 100)
TH1D * b1 = new TH1D(“b”, “b”, 100, 0, 100)
I have tried to select Add from the contextual menu of the h1 and insert the value h1 and b1, or the name of the histogram h and b without result.
Thank you very much for your help.
Best regards
Andrea Bulgarelli
