A free application, called GRAPHER, has been available to Mac users
since the OS 10.4 was introduced, about 3 years ago. I am learning how
to use this application on my new iMac (under OS 10-5.2). Unable to
find a good tutorial (by googling) I am experimenting by trial and
error. That is not the best way to learn things. Who else is using
Grapher? What do you think about it? Please share the URL of a good
tutorial, if you know it.
