I have saved into a root file an array of histograms (let say hist, hist, etc.) and now I am trying to plot some of these histograms.
When I open my root file using a TBrowser, I can draw these histograms simply by clicking on the corresponding icons.
However, when I try to plot these histograms from a macro or from an interactive root session (after opening the histogram file, via the command hist.Draw(); ) I am not able to draw the histograms. The strange thing is that in my root file I saved not only histogram arrays, but also some “simple” histograms, and I can plot these histograms via the command histogram.Draw().
Can somebody help me?
