Problems with TGraph2D and pcol (and zcol)

[IzaakWN]

Hi @couet, thanks for the reply. The problem I had was exactly the one from here:

TGraph2D: logarithmic z-axis

Now fixed in master: { TCanvas *c = new TCanvas("c","Graph2D example",0,0,600,400); Double_t x, y, z, P = 6.; Int_t np = 200; TGraph2D *dt = new TGraph2D(); TRandom *r = new TRandom(); for (Int_t N=0; N<np; N++) { x = 2*P*(r->Rndm(N))-P; y = 2*P*(r->Rndm(N))-P; z = (sin(x)/x)*(sin(y)/y)+0.2; dt->SetPoint(N,x,y,z); } gStyle->SetPalette(1); gPad->SetLogz(); dt->SetMarkerStyle(20); dt->Draw("pcolz"); c->SetPhi(0.00001); c->SetTheta(0.0…

I managed to switch to root 6.12/07, and I managed to get it working as expected.
