GnuplotInterface is a class that enables the user to easily plot values in Gnuplot. It handles both the connection to Gnuplot and performs the window management as well. It creates a text-file in which the location of the Gnuplot executable can be entered (without recompiling the program).


I only got this interface to work under MacOS

The one function that this class is built around is the popen function. This is a non-standard function to open a pipe. If this function is unknown under your programming environment, try either std::popen, std::_popen, std::__popen, popen, _popen or __popen.
