This is a modification of the gnuplot_i library by N.Devillard, which enables the following functionality:

• 3D plots, using gnuplot_splot(handle,x,y,z,n,"title");
• Setting z-axis labels with gnuplot_set_zlabel(handle,"z-axis label");
• Production of colour PostScript files with gnuplot_hardcopy_colour(handle,"graph.ps");
• Windows support - added in September 2005.
• Plotting of complex structures through the use of callbacks - see gnuplot_plot_obj_xy and gnuplot_splot_obj in gnuplot_i.c.
• Contour plotting, using gnuplot_setstyle(handle,"lines");gnuplot_contour_plot(handle,x,y,z,nx,ny,"title");
