Subject: Problem in adding two TGraphs in the same pad using <Argus> block in tabbing 
I tried to reproduce the problem with using histoGUI example.
However I couldn't reproduce it; namely two graphs are shown.

I attached a modification for the example, which I applied for the test.

If you attach something similar which can reproduce the problem, it will be easier for me to find the reason.
