Igor. If it still exists, it's the best graphing program available for Mac.
A little ad I got about one year ago (yes, they bothered to answer my mail):

Igor is unlike any of the graphing programs you mentionned.
  It is strictly for technical users.
  It handles large amounts of data very well.
  It has very powerful number crunching capability.
  It has a powerful macro language for automating tasks.
  It is on the complex side, most appreciated by "power users".

Cricket Graph. Computer Associates announced a new, much improved version
2.0 of Cricket Graph. I don't trust them, they are too much MS-DOS oriented.

Mathematica. It has beautiful graphics.
Statistica. The same. Both are so expensive and feature loaden it would
be money wasting to buy them just for graphing.

Hope this can help,
