But instead of switching modes, it starts a new window, with a gnome-canvas in it. The 'graph' lib then sends its graphic commands through a pipe to the new window. It is far from usable (many things are missing) but the idea has several pluses (in my opinion): 1) The 'remote graph' can be called from other programs as the interface is just the pipe. I could even be called from bash... (never tried) 2) The gnome canvas has nice anti-aliased graphics, and the resulting plots _do_ look very nice. As I said, it is far from complete (eg. no fonts yet) and not very stable either. One thing I haven't found yet is a way to save the gnome-canvas to a graphics file (I just made screen shots). With the experience I had later with gnome-print library, I could image that this could also be combined somehow. Is there interest in this?
