interactive gnuplot

[<man...@il...>]

Hi,

We are using gnuplot 4.0 under linux within a python script. To do that, we=
=20
just run gnuplot and send commands through a pipe connected to its stdin.

But, in this mode, we don't have interactivity (mouse, zoom, etc..), but it=
=20
works well when lauching gnuplot from a shell.

Gnuplot probably enters in a special mode when not launched from a shell. I=
s=20
it possible to turn out this behaviour, and have interactivity even when=20
launched from a pipe ?

Thank's,
