	Gnuplot ()
	Default constructor.
	Gnuplot (const string &_style)
	Set a style during construction.
	Gnuplot (const string &_title, const string &_style, const string &_xlabel, const string &_ylabel, vector< double > _x, vector< double > _y)
	Constructor calling plot_xy().
	Gnuplot (const string &_title, const string &_style, const string &_xlabel, const string &_ylabel, vector< double > _x)
