Re: TH3 constructors with both constant and variable bin widths...

I think I might have found a solution. If I want to define a TH3D having only variable bin width for the x axis, could I simply do the following?

Double_t nbins=10;
Double_t bins[]={0,1,2,3,4,5,6,7,8,9,10}; TH3F th("th","th",nbins,bins[0],bins[nbins],10,0,10,10,0,10); th.GetXaxis()->Set(nbins,bins);

Thank you!
