Re: [Gnuplot-info] call gnuplot from c++ (windows)

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

Hello

GNU octave for windows uses gnuplot.exe.  --persist option is not used.

How about fflush(pipe); at each command to flush buffer ?.

*************************
FILE *pipe = popen("gnuplot","w");

//adjust settings
fprintf(pipe, "set palette gray negative\n");fflush(pipe);

//plot
fprintf(pipe, "plot 'fileX.txt' matrix with image\n");fflush(pipe);


//close gnuplot pipe
pclose(pipe);
*****************************************
Regards

Tatsuro
