Hi,
This option already exist. Try the following macro:
void hist3d() {
TH3F *h3 = new TH3F("h3","h3",20,-2,2,20,-2,2,20,0,4);
Double_t x, y, z;
for (Int_t i=0;i<10000;i++) {
gRandom->Rannor(x, y); z = x*x + y*y; h3->Fill(x,y,z);
h3->Draw("");
}
The Draw() method can be used with the "box" option to produce a 3D box plot, or with no option to produce a 3D scatter plot. Thanks to the canvas menu View/View_with you can display the 3D plot either with x3d or GL.
Cheers, Olivier
