Dear Erica,
Thanks for the tip. I have been thinking about using GNUPlot or like
as some kind of preliminary way to view my Cocoa generate data.
AquaTerm appears, at first glance, to be a way to integrate this
approach directly into Cocoa. However, I think what it need is a Cocoa
API that generates simple plots of data, like you find in a spreadsheet
program (say, MS Excel). I do not know if such an API already exists
in Carbon or OpenGL that we can access through Cocoa.
There are such API for Java, as mentioned previously, that one could
access through the Cocoa's Java bridge. Yet the most advanced one
VisAD was not compatible with OS X post 10.1 (I have not checked the
new Java 1.4.1) and furthermore, I believe that OS X Java 1.4.1 still
does not support 3D. Furthermore, I suspect most programmers would
greatly prefer native graphics over Java graphics, which are usually
slower, and while Cocoa's Java bridge itself is great feature, I choose
only when absolutely necessary because I do not consider it to be
robust.
Truly yours,

Hello Oleg, John,
Forgive me if I misunderstand to your needs completely, but would this
help at all?

Dear Oleg,
I am also looking for some kind of scientific charting / plotting
graphics toolkit to use in Coccoa.
For Java programming, I have used Visad:
http://www.ssec.wisc.edu/~billh/visad.html
which is very well developed but not compatible with the OS X since
10.1 (but I have not tried the new Java 1.4.1 just released by Apple).
So, I switched to SGT:
http:www.epic.noaa.gov/NOAAServer/sgt/
which is only 2D (as is Java on OS X at this point in time).
