The above sounds like a description of the PRL libraries - source
included, no royalties, good documentation, plenty of test/demo
programs, and free support and upgrades for 1 year.  Most PRL libraries
are only slightly higher than $45 (but not much more), unless you
run Linux, in which case a free binary version is available.  The
main difference is PRL is supported under Fortran rather than C,
although some users are calling it from C, and at least one user
is driving it from Ada on a VMS Alpha system.

So maybe it's a coin toss between ZGRAF and PRL, but maybe not.
To find out, check his web page and download his documentation and
demo code, and then check PRL at http://www.iah.com/oa/ and download
the PRL docs and demo code for Linux (it's the same on all systems).

After that, post your opinions.  Be interested in hearing them.
