Dear ROOTers,
In my ROOT usage I encountered many times situations where say 10 different histograms need to be compared, but having them all displayed in a canvas at the same time would clutter up the canvas and not allow comparing them efficiently. Currently what I need to do to effectively compare all 10 histograms is to change the macro with which the canvas is created to draw only a few histograms at a time and change that in permutations until I have compared all 10 histograms with each other.
In contrast, an ability to draw only a few of all histograms stored in the canvas at a time, and change that subset interactively, would greatly enhance efficiency of getting all information out of the 10 initial histograms and how they compare.
The current default of drawing a TCanvas stored in a TFile is to draw all objects attached to that canvas (histograms, graphs, legends, lines etc). I wanted to ask if there is an existing extension (or if not, maybe that extension could be added) to the TBrowser application which displays a list of all objects in the active TPad of a canvas. The extension would display all objects, one per line, with a checkbox next to each object. Once a checkbox is checked/unchecked by the user, the TPad would redraw or update and only display the selected objects.
Such an extension would speed up my work by a lot- it would be great if someone could look into this.
Thank you very much,
Best regards,
Martin
