I want to draw a 1D histogram on the top of a 2D histogram. The script attached is doing exactly what I want to do. The only problem is that I don’t like the artifacts which Draw(“cont”) produces, and I want to use “cont4” instead. When trying to change in the script “cont” to “cont4” I am loosing my 1D histogram (or at least most of it). Any idea why? I guess that the cont4 option is changing something in the gPad, but I do not see why “cont4” is doing that and “cont” is not?
Attached you will find a working macro. CONT4 use a special algorithm which does allow simple drawing using “SAME” on top of it. It is on our todo list to improve it.
Thanks a lot. It works. For one pad. I have actually a canvas with a few TPads on it. On two of them I tried with the help of your example to draw the output from two different histograms. What I was surprised to see was the Draw(“cont1”) from the second histogram on the top of my first histogram. To visualize what I mean I changed a little bit yous script. It is visible on pad6_4 that the cont1 version of the histogram was once more drawn on top of the 1D histogram. How can I avoid that?
Attached is the corrected macro. Note that I used DrawClone instead of Draw because you are using always to two same histograms. If you have different histogram you can use Draw(). cont4same2.C (83.7 KB)
