[Gnuplot-info] Memory overload in real time plotting

[tryfonaration <far...@gm...>]

Hello,

I am using a simple C library from here http://ndevilla.free.fr/gnuplot/ to
plot real-time data with gnuplot. It basically opens a pipe to gnuplot and
you can feed it with data and commands. I want to plot an image that changes
periodically. I make the following command string "plot '-' matrix with
image", then concatenate a big chunk of data and then pipe it to gnuplot.
This is done every a few seconds. What happens is that my program occupies
more and more memory every time a new command is issued and eventually the
OS kills it. 
Any idea why this could be happening?
