Just to give you an example. I ran both the Coyote Graphics and Function
Graphics basic line plot routines first to "initialize" the system.

Then I timed just the time to produce a plot.

Coyote Graphics: 0.0300 ; Probably slow because of circle symbol
Function Graphics: 0.0268

Then I timed the time to produce the plot and make a PostScript and PNG
file:

Coyote Graphics: 1.672
Function Graphics: 4.398 ; Probably slow because of big PNG file

If I make a big PNG file with Coyote Graphics, then I get a time of
3.091.

So, I don't know. My impression is always that Function Graphics
routines are slower, but I have no idea how MUCH slower. I think if you
have a reasonable high tolerance for complicated things not always
working right, you are probably OK with function graphics. In my tests
of hardcopy output (the only thing I really care about, usually), I find
Coyote Graphics work more intuitively than Function Graphics and produce
identical results. When I build applications that are to go in front of
a user, I tend to use object graphics, but only because I find these a
little more reliable than function graphics. (The pressure plot saga of
this morning seems to happen to me a LOT when I use function graphics. I
think I must have an undiscovered and unintentional talent for breaking
those things!)

Cheers,

David
