I have a problem opening histogram whose name has a hyphen in its name.
histogram name: ggd-bg
When I try to display the histogram with:
root  ggd-bg->Draw(“colz”)
I get the following error:
Error: Symbol bg is not defined in current scope (tmpfile):1:
Error: Failed to evaluate bg->Draw(“colz”)
*** Interpreter error recovered ***
Are names with a “-”(hyphen) forbidden in ROOT?
