[Gnuplot-info] gnuplot in subprocess via pipe

[Kilian S. <ml...@on...>]

Hi,

I am very new to gnuplot and its quite fun!

Currently trying to integrate it with another command
line application I already got the mouse working... :)

I read somewhere you have to put
set mouse
in .gnuplot

So I am actually talking to gnuplot with a pipe from a c program,
which wants to show a series of plots in succession, (restarting gnuplot
again and again).

Currently, I am using something like sleep 3 in this c loop
to be able to see the plot.

I like the q key in x11 to close the plot -- my question is,
if there is a way to actually quit the gnuplot process using this key.

Then I could choose as a user how long I want to look at a plot, zoom in etc
and then hit q to see the next one...

My c program uses waitpid then...

Thanks for any hints,
cheers,

  Kilian

There's ctrl-q, Invented for exactly that purpose.

OTOH, if you want to wait for a user interaction, then go on plotting, 
maybe you should consider 'pause mouse' instead.

Thanks for the hint!
I compiled the cvs from source and the ctrl-q is functional now,
before it did not do anything, but it seems to act exactly like q,
meaning just closing the x11 window and putting me back to gnuplot>.

I'll need to look into the docs to see what you mean.

Thanks!!

I feel trying to force gnuplot to do something arkward...
'pause mouse' does not really help because I would like
to use the mouse for zooming - when I try to terminate
on a keystroke I need to use reread, which only works
on loaded files, but I am talking from the pipe...

I wonder what the natural setup would be for using gnuplot
in a subprocess....
