[ROOT] 2D color plot

Hi all,
	I can't seem to be able to make a thermal plot of a
2d histogram. Here is a simple example:

ghist = new TH2F("Gaussian","This is a gaussian",10,-10,10,10,-10,10);
gRandom->SetSeed();
for (Int_t i = 0; i < 1000; i++) {ghist->Fill(gRandom->Gaus(0,5),gRandom->Gaus(0,5),1);}
gStyle->SetPalette(1);
ghist->SetContour(28);
ghist->Draw("colz");

I get a palette with 2 colors and a blank plot! Is this a bug or am I
doing something wrong?

thanks,
