Re: [ROOT] Making Postscript plots without drawing a Canvas

Hi Miro,

Simply run Root in batch mode. You will not get graphics on the screen,
but you will still be able to print your TCanvas on a ps file. Example
cd $ROOTSYS/tutorials
root -b
root > .x gerrors2.C
root > c1.Print("c1.ps")

You can also do  root -b -q myscript.C
