I have tried: { gROOT->Reset(); TCanvas *c1 = new TCanvas("c1","Test",0,0,600,600); fun2 = new TF2("fun2","x+y",0,3,0,3); fun2->GetXaxis()->SetNdivisions(80 + 100*4); fun2->Draw("cont"); } > 2.

For the time being none of the contour options are able to do that automatically. Cheers, O.Couet -- Org: CERN - European Laboratory for Particle Physics.
