Save TMVA plot in png

TMVA

Hi ferhue,
it does not work either.

The last idea I can think of is to call

cout << TMVA::gConfig().fVariablePlotting.fUsePaperStyle << endl;

AFTER opening the GUI but before pressing the export button.

And maybe post your version of tmvaglob.cxx.

Dear Ferhue,
can you please tell me where I can find the tmvaglob.cxx file?
I’m using the ROOT TMVA v6.06 and I can’t find it [1].
Regards

locate tmvaglob.cxx /opt/root/root_src/tmva/tmvagui/src/tmvaglob.cxx

If you edit the file, you need to call “make” again.

Dear ferhue,

“locate” returns nothing as well as “find”, so I do not see where this file is.
I did not download the TMVA package but I’m using the root TMVA.

Did you install the ROOT from source or downloaded as a binary?

If you want to edit tmvaglob.cxx, you need to build from source.
