Saving TH2D to *.C results in TH1 object (root 5.20)

ROOT

Hi,

I noticed a problem concerning TH2 objects.
When I save in root 5.20 a TH2D histogram into a C-file the histogram-object is saved in the C-script as a TH1 object. Anyway, since TH2D is a daughter of TH1 it is not a real problem as long as you do not try to use a specific TH2D function (as ProjectionX() for example).

i.e. in the saved C-script the histogram-object is called

In my case - for bringing ‘ProjectionX()’ back to life - I changed in the C-script TH1 to TH2(D)

Cheers,
Thomas

Hi,

This has been changed in revision 29731 of the trunk (i.e. using the specific type to declare the pointer).
