DrawGraphLabel()

void chrono::ChFile_ps::DrawGraphLabel	(	double	dx,
		double	dy,
		double	fontsize,
		char *	label,
		int	dolinesample,
		bool	background = true,
		double	backwidth = 3.0,

If "dolinesample= true", also draws a little horizontal sample of line with current width/color on the left of the label.

DrawGraphXY()

void chrono::ChFile_ps::DrawGraphXY	(	const ChArray<> &	Yvalues,
		double	Xfrom,
		double	Xstep
	)

Draw a line into graph viewport, where the y coords are into an array and x coords run form Xfrom...
