I was going to illustrate the difference between the old way of doing
things and the more modern way, but the first file I downloaded (for a
filled contour plot) uses a routine, Gauss2D, that I can't find in any
of the "required" libraries.
Any ideas where I might find this?
Cheers,
David

I guess I'm a LITTLE bit sympathetic about setting up the PostScript
device. God knows, once you get that working you don't want to change
anything, even if your 25-odd commands can be reduced to 2.
But, the thing that causes me a LOT of grief and time is setting Coyote
Graphics color keywords with cgColor, like this:
cgPlot, data, COLOR=cgColor('blue')
DON'T DO THAT! DON'T EVER DO THAT!!
Here is the way go set color keywords in Coyote Graphics commands:
cgPlot, data, COLOR='blue'
Otherwise, nothing but havoc ensues despite my best attempts at
preventing it.
I would pay someone good money to get that fixed on that web site. It
would pay enormous dividends for me. :-)
Cheers,
David

I really like the idea behind this page and wish there were more of them available on the web.
In a previous life (!) I used python/matplotlib to generate various plots. For those not familiar with the matplotlib package it has a superb gallery page (matplotlib.org/gallery.html), much like the astrolib page.
Quite frankly.... Find the plot closest to your requirements and *borrow* the code. Sounds cheap but it really helps when learning or trying to do something new.
Keep up the good work.

Oh, dear! Coyote Graphics examples circa 2005, it looks like. :-(
