I’m a complete novice in ROOT and I apologize if the following query happens to be a misplaced one. I’m trying to read/calculate data points for three plots in one canvas. (Actually, the data points are directly read from the inout file for one plot and the data points for the other two are calc…

@couet can you give a hand with this? Thanks!

On which platform ? try to update the full canvas: draw_trace->Modified(); draw_trace->Update();

Thank you very much for your suggestion. However, I’m afraid, the problem persists even after implementing the change. I’m working on Linux Fedora 25.

Can you provide a small reproducer ?

[rraut_code1] I realize that I might not be providing sufficient info to facilitate a solution and do apologize for the same. The data files on which the code works are inconveniently sized for sharing. In the absence of such options, I’m uploading the screenshots that might represent the problem…

[image] Drawing histograms on a TCanvas in a Loop ROOT Hi I’m trying to compare 2 histograms visually. When drawing single histograms on a single canvas (or different canvases also) I have no problem. However, if I try to do it in a loop (try to change histograms throug…

I’m extremely sorry but I could not make this fit in the context of my problem. This is owing to my own deficiencies in this domain and I remain apologetic for the same. Could you please elaborate on the solution ? And I shall also remain eager to see what @couet has to say. Gratitude !

I think the link @Wile_E_Coyote sent you might allow you to draw this histograms in a loop. Have you tried to use your code in ROOT interpreted ? When I asked you for a 'reproducer" it was just a small macro we could run interactively reproducing the logic of your code. The one you sent initially …

@couet It seems to me that this is a classical problem of "blocking I/O” (the same as in the thread I mentioned in my previous post ). @rraut If you do not want to solve it properly, you can try a “brutal fix” (which may or may not work) … after the last “Update” call (and / or before you start to w…

@Wile_E_Coyote seems to me also.
