I have a code that use ROOT 6.20 and some part of it call for RooDataSet::createHistogram which doesnt exist in ROOT 6.30 how can I make it work for 6.30
ROOT Version: 6.30/04 Platform: Red Hat Enterprise Linux release 9.3 (Plow) Compiler: g++ (GCC) 11.4.1
Thanks for the interesting post.
The overload that takes as input integer parameters has been removed: more details in the release notes.
You can always use the overload taking RooFit command arguments: documentation here.
