THStack Y-axis range offset

Trouble w/ StackHistograms

Hi, I guess this issue is solved on my side. I just wanted to expand this old post: If I do: THStack* hs = blah; hs->Add(…); Then If I want to edit the y-axis and draw: hs->SetMaximum(600); hs->Draw(); As the previous post says the result is not 600, but slightly more based on ‘gStyle->GetHistTopMargin()’. But if one draws the stack in log mode, they must be weary of what is being done behind the scenes: root.cern.ch/root/html/src/THStack.cxx.html#717 and root.cern.ch/root/html/sr…

I just draw a dummy hist with my axis range and then the stack. Couet has another solution in the post. You can see the code in THStack that is causing you the trouble. The code attempts to automatically set pleasing yaxis limits.

Cheers,
Justin
