[Gnuplot-info] Auto-Closing gnuplot on closing the gnuplot window

[Gunter K. <gu...@pe...>]

Dear all,

wxMaxima allows to automatically embed gnuplot plots into a maths
worksheet: The plot is generated with the png (or pngcairo) terminal and
the bitmap is embedded. Tomorrow's nightly build also on right-clicking
a plot allows to start a separate gnuplot process - which popups a
window in which the user can interactively turn a 3d plot, zoom in and
out or measure coordinates with the cursor. There is a problem left, though:

- If I start gnuplot as "gnuplot -p /tmp/maxoutXXX.gnuplot" gnuplot
closes when the user closes gnuplot's plot window. But the displayed
graphics is is not interactive (for example a 3d image cannot be turned
using the mouse)
 - and if /tmp/maxoutXXX.gnuplot ends with a "pause -1" the image can be
turned with the mouse. But in this case gnuplot doesn't close when the
user dismisses the interactive gnuplot window, which makes gnuplot act
like a big memory leak.

In the internet I find many related questions like

...but until now I didn't find a real solution to my question (most of
the questions were from the gnuplot 4.0 times, though) so I'm asking here.

Thanks in advance,
and kind regards,

    Gunter.
