Hi,

    Is there any way to check if a histogram has been created or not?

    I am thinking something on the same line that I can do for a canvas:

            TCanvas *myCNV = (TCanvas *)gROOT->GetListOfCanvases()->FindObject("myCNV");
            if (!myCNV) { myCNV = new TCanvas("myCNV","myCNV",920,630); }

    It doesn't seem to work for histograms.

    Thanks!

Stelios.
