[Gnuplot-info] proporsal of pgnuplot patch

[Tatsuro M. <tma...@ya...>]

Hello


The current octave for windows distribution, the Michael's modified pgnuplot was used.
That is independent of wgnuplot and which has both abilities of pipe receiving and the plotting
system.
  That is because the current octave all plotting data to the gnuplot via pipe.   The combination of
the pgnuplot and the wgnuplot cannot be used.  The incoming data speed is fairly larger than the
wgnuplot interpret the command from the wgnuplot command terminal.

However we sometimes want to use the latest version gnuplot like cvs one for example distributed by
prof.Kakuto.

The patch attached that used in the test for the successive plot from the octave.

I think that the current pgnuplot is not suitable for this purpose and not effective.
The command will be better to be interpreted by line to line.  
I have set waiting factor by each line.
I used the Sleep function, however even sleep(1), the wait time is enough but it can to be shortened.

I consider for this patch is for a general patch  but not only for octave.
The reason is the gnuplot 4.2.0 suffured from the pipe line problem.
It was solved at the gnuplot 4.2.2.
However, for wgnuplot, the situation is quite different.
For wgnuplot, the pipe line treatment is carried out in the pgnuplot.
In my opinion, for wgnuplot, the pipe line problem should be treated in the pgnuplot.
 

I would like to hear the gnuplot persons' opinions.

Sincerely yours,

Tatsuro MATSUOKA
