Re: color palette ID

Hello Luca,

There is an example here, some code I wrote a long time ago (look at this member --> void MPXViewer::setHistoPalette(Int_t visMode) )  

http://atlaspc4.lps.umontreal.ca/cgi-bin/viewcvs.cgi/idarraga/medipix/MediPixAnalysisCore/MPXViewer/MPXViewer.cpp?revision=1.25&view=markup

it should be self explanatory ... look specifically at the private member "palette".

cheers,

John Idarraga
