Announce: Plotting Widget for MacTk (alpha release)

[Vince Darley]

Hi,
I've ported Plplot's Tk widget to work on MacOS. This is only an
alpha release, and there are some known bugs, but it generally works well.
Go to my web page: http://www.fas.harvard.edu/~darley/Pltk.html for a
couple of screenshots, and some example Tcl code.

Brief summary: Plplot is a platform independent plotting toolkit
supporting 1d,2d and 3d plots. It is distributed under Gnu's library
license. If you've used plplot's Tk interface under X-windows, you'll find
I've basically ported it over, but have had to remove a few features in the
process (stuff like cross-hair cursor over the plot to zoom in/out and
select regions). Hopefully these will gradually make it back in (help,
please?)

It compiles fine with CW9 on PPC as a loadable Tcl extension to Tk,
and by default requires Itk. However you can #undef 'NEED_ITCL' and
'NEED_ITK' and then it'll work fine without. You can control Plplot from
C, C++ or Tcl and there are even interfaces to, e.g. python and fortran.
