Plot 3 histograms on the same canvas

ROOT
1

Hi,
I have 3 histograms. They are corresponding to to the up-limit of an uncertainty band, down-limit and the center distributions. Now I am trying to plot the band with color in gray and the center histogram in line. What I did is plot up-limit one with filling color in gray and then overlapping down-limit one with filling color in white, such I got a band, at last I overlap the center histogram on the same canvas. Please look at the example code attached. For the plot, I have two problems:

  1. ticks of x and y axises have been covered by the 2nd histogram which color is in white
  2. One part of the edge of Yaxis is covered too although I use the drawing option “][”.

I am wondering how to handle this kind of problem? Thanks.

Zhiyi.

Use a THStack. See your script modified accordingly.
