For the record, I posted a patch for gnuplot under Win32, see
http://sourceforge.net/tracker/index.php?func=detail&aid=1627936&group_id=2055&atid=302055
The problem appears while piping data to pgnuplot.exe. When a lot of
data is used, gnuplot
suffer data loss. This is due to the internal of pgnuplot, which
overflows to event queue of
wgnuplot.exe, without checking that messages are actually sent.
The patch I proposed allows the compile gnuplot into a mode similar to
UNIX, with
real pipe communication. The result is a faster communication with
octave and no
data loss anymore.
I don't know if this patch will find its way into the main source tree,
so I post it here
for the record. I plan to include the modified version in the
pre-compiled Windows
package of octave.
Bye.
Michael.
