Hi Maurizio,
One of the new features of the recently released version 2.23/09
is the drawing of the 3-d axis for 3-d plots.
You can do, for example
Root > ntuple.Draw("x:y:z"); //this produces a 3-d scatter plot with axis
Root > TH3F h3("h3","a 3-d histogram",20,-1,1,10,-2,2,30,-3,3);
Root > h3.Draw(); //this draw 3-d axis only (empty histo).
Root > // fill the histogram
Root > h3.Draw(); //shows a 3-d scatter plot (view it with X3d or GL)
Root > h3.Draw("box"); //show 3-d boxes
Root > TPolyMarker3D pm3(...); //create a 3-d polymarker object
Root > pm3.Draw(); draw pm3 in teh current 3-d pad on top of histogram
Root > etc..
