[Gnuplot-info] Pgnuplot again

[Teodoro S. <te...@ii...>]

Hi!

This is how I'm supposed to work with pgnuplot.exe:

FILE * plot_pipe =3D _popen("pgnuplot.exe", "w");
fprintf(plot_pipe, "plot x\n");

But when I do this nothing happens...

I did this in desperation:

FILE * plot_pipe =3D _popen("pgnuplot.exe", "w");
for (k=3D0; k<10000; k++)
    fprintf(plot_pipe, "plot x\n");

And it worked!! But it sends "plot x" hundreds of times...
Then if i write another fprintf out of the "for" sentence, it is not =
piped to gnuplot.

I'm totally lost. How can I work with pgnuplot.exe in a "clean" way??
