Re: [ROOT] Simple question on graph draw options

Hi Mina,

Currently TGraph::Browse uses the hardwired option "alp".
In the CVS version, I have modified this function.

By default the option is "alp" and can be modified by:
  -adding a line in system.rootrc with 
   TGraph.BrowseOption:  myoption

  -calling gEnv->SetValue("TGraph.BrowseOption",myoption)
