Getting info on histogram composition in saved .root files

I have saved a canvas with few histograms as a .root file. Can I see the number of events in each histogram separately now or not? I tried to use Inspect, but it didn’t helped.

Thank you for the hint, but is there a way to do it using GUI?

Try with a mouse … after you have the canvas drawn, move the mouse cursor to one of the drawn points and click it with the right mouse button -> a new menu should appear (it’s title will tell you which histogram it is) -> use the “Dump” or the “Inspect” menu entries.
