Some of this code is good. Some of this code is very bad. It is a prototype,
nothing more, nothing less.

Particularly bad/nasty/unreadable code is in main.c. It is also Linux specific.

UberGraph - A realtime graph similar to that found in Gnome System Monitor.
            However, it is much faster and smoother. It runs at a higher
            framerate with less X bandwidth.

            It uses multiple pixmaps on the server-side and shifts data between
            them to lower the X bandwidth.  New data is rendered and clipped so
            that the transfer is small.  If frame movement is < 1 pixel, the
            framerate is dynamically reduced.

UberHeatMap - This is going to eventually be similar to UberGraph but as a
              heat map.  It's not very far yet, however.

GRing - A small circular buffer meant for values in the realtime graphs.  This
        is most definitely not meant to be used as a byte buffer, so don't use
        it as such.

        Example:

           GRing *ring = g_ring_sized_new(sizeof(gdouble), 60, NULL);

           or

           static void free_array_func (gpointer data) {
           	GArray **ar = data;
           	g_array_unref(*ar);
           }
           GRing *ring = g_ring_sized_new(sizeof(GArray*), 60, free_array_func);

Something went wrong with that request. Please try again.
