Simple C++ interface for Gnuplot with stream ability like std::cout and so on.

Small but it supports the full functionality of Gnuplot.

For Linux only! Sorry.

Example:

#include <gnuplotstream.hpp>

using namespace std;
using namespace gpstr; // Namespace for Gnu-Plot-STReam

int main( void )
{
   cout << "Minimal test-program plotting the function si(x)" << endl;
   try
   {
      PlotStream plot( "--persist" );
      plot << "plot sin(x)/x" << endl;
   }
   catch( exception& e )
   {
      cerr << e.what() << endl;
      return EXIT_FAILURE;
   }
   return EXIT_SUCCESS;
}

Result:

If PlotStream has to invoke Gnuplot with additional command line options, then these options are the first parameter of the constructor of PlotStream.

Example:

PlotStream plot( "-noraise --persist" );

Alternatively you can define the macro GPSTR_DEFAULT_OPTIONS in your makefile.

By default the class PlotStream expect the executable of Gnuplot in /usr/bin/gnuplot. If Gnuplot has been installed in a other directory, then the executable file has to be the second parameter of the Constructor:

PlotStream plot( GPSTR_DEFAULT_OPTIONS, "/path/to/my/gnuplot" );

or:

PlotStream plot( "-noraise --persist", "/path/to/my/gnuplot" );

Alternatively you can define the macro GPSTR_DEFAULT_GNUPLOT_EXE in your makefile which will overwrite the default.
