Dear ROOT team,
I’m working on visualizing 3D probability density functions using TH3F histograms. When I use Draw("ISO"), I get a solid surface, but I would like to apply a color gradient (heatmap style) to better reflect the variations in density or intensity across the surface.
Is there a way to do this in ROOT?
I’d really appreciate any guidance.
cMain->cd(3);
hist->SetTitle("Density 3D ");
hist->GetXaxis()->SetTitle("X");
hist->GetYaxis()->SetTitle("Y");
hist->GetZaxis()->SetTitle("Z");
hist->GetXaxis()->SetTitleOffset(2.0);
hist->GetYaxis()->SetTitleOffset(2.0);
hist->GetZaxis()->SetTitleOffset(1.5);
hist->SetFillColor(kBlue);
hist->SetLineColor(kBlue);
hist->Draw("ISO SURF2");
Thank you everyone.
