I tried working with the information from your tutorial, but I
consistently get an error.
Here's what I do: (both interactively and from scripts.)
TFile file("Science.root");
TCanvas can("can","a0:a1",700,500);
TPostScript ps("b_0.ps",112);
bgoadc.Draw("a0:a1","lay==0&&cry==0");
bgoadc.Draw("a0:a1","lay==0&&cry==1");
ps.Close();
can.Close();
.q
Instead of getting 2 pages in the .ps file, I get 4, with 1 and 3 blank
and 2 and 4 the desired pages.
Does anyone know how to fix this?
