    Yes, It is not available for Mac due to very simple reason - Helmut
Michels  (DISLIN creator)  has no Mac in his institute.

DISLIN contains so called 'quickplots' which are ideal for your purposes.
The following simple example plots a function on the screen

from Numeric import *
from dislin import *
x=arange(100)
qplot(x,sin(x/5.0),100)

To save a plot in Postscript you should add  line

metafl("post")

before calling qplot. There are similar one-line functions for plotting 3D
colour plot, surface plot, contour plot, etc. I think it exactly the thing
your students need. You can find more information about using DISLIN with
NumPy in the SHORT article at
