A trivial gnuplot interface for c++.

There are many libraries providing the same solution, such as gnuplot-iostream. gnuplot-cpp aims at being lightweight and super easy to use. It functions by piping data to a gnuplot subprocess.

• Header only
• Lightweight (~50 lines of code)
• Easy to use

#include "gnuplot.h"
int main(){
 GnuplotPipe gp;
 gp.sendLine("plot [-pi/2:pi] cos(x),-(sin(x) > sin(x+1) ? sin(x) : sin(x+1))");
 return 0;
}

Result:
