Hi,
If you do not have yet a canvas on the screen, do
gROOT->SetBatch(kTRUE);
if you have a canvas, TCanvas *canvas, do
canvas->SetBatch(kTRUE);
When running in batch mode, you can continue to call your scripts doing
graphics and generate postscript, eg
canvas->SetBatch(kTRUE);
myhist->Draw();
canvas->Print("canvas.ps");
canvas->SetBatch(kFALSE);
anotherhist->Draw(); //now on th screen
Note that a canvas can be in batch mode and another canvas with graphics
on the screen.
