Example:
{

   TCanvas *c1 = new TCanvas("c1");    

   TH2F *h1 = new TH2F("h1","h1",40,-4,4,40,-4,4);    TH2F *h2 = new TH2F("h2","h2",40,-4,4,40,-4,4);    Double_t a,b;
   for (Int_t i=0;i<5000;i++) {

      gRandom->Rannor(a,b);
      h1->Fill(a-1.5,b-1.5);
      h2->Fill(a+1.5,b+1.5);

   }
   TExec *ex1 = new TExec("ex1","gStyle->SetPalette(0);");    TExec *ex2 = new TExec("ex2","gStyle->SetPalette(1);");    h1->Draw("colz");
   ex1->Draw();
   h1->Draw("col same");
   ex2->Draw();
   h2->Draw("col same");
}

Hello ROOTers,

I have a question about using two palettes in one canvas. I found a similar topic from the RootTalk archive that was posted 7 years ago. http://root.cern.ch/root/roottalk/roottalk01/1543.html

What is the best solution in 2008?
