Hi,
Thanks for the indication.

I solve my problem with pstricks add.

For information,
My file has this format :
t x y z

My file has 4 columns >> plotNoMax=4.

The first column is always used for x-axis.

To plot y in fonction of t, the command is :
\listplot[linecolor=red,plotNo=2,plotNoMax=4]{\Data}
