I'm making a program in Visual C++, .NET edition, and I would like it to =
plot a function.
I don't know if this is the right way to do this, but this is the code I =
_popen("pgnuplot.exe plot x", "w");
(This is an example to plot the function y=3Dx.)
This codes always generate: "Can't find the gnuplot window".
What am I doing wrong??
