The PHPlot Contributed Code directory contains code you might find useful
with PHPlot, but that doesn't quite belong as part of PHPlot itself.

You will have to read the comments in the code files, and see the example
files, to determine what these do and if they are useful to you. None of
these functions is documented in the PHPlot Reference Manual.

You may include or paste these functions into your own scripts. Check the
files for details, but some of these are considered "public domain" with no
usage or license restrictions.
