[pstricks] Plot files

[Xavier Pessoles]

Hi,

I am a newbie and I would like to know how to plot a file with pstricks :

My data file have 4 columns (t,x,y,z), and I would like to plot
x y and z in fonction of t.

My file can reach more than 10000 lines.

Moreover, I wish I knew if it is possible to manipulate data :
I would like to plot, for exemple :
x+50 in fonction of t.


I hope that my questions are undertandable...

Thanks for your help.

Xavier.
