Data-plotting program for II?

[mike@athena.mit.edu (Michael T Decerbo)]

I would like to use my Apple II to plot and print graphs and, maybe,
calculate regressions, given a bunch of input data points. This is
what, for example, Cricket Graph will do on a Macintosh.

Does there exist such a program that I can use? Where can I find it? 

I have an Apple IIgs with 512K of RAM and an ImageWriter II printer.
Will I need more RAM?

Thanks for all your help.  I've always appreciated the thoughtful
pointers I've gotten from folks on this newsgroup.
