MP Graph and texnum.mpx

["Adam Lindsay" <atl@comp.lancs.ac.uk>]

Hi ConTeXters,

I've been using the MPGraph part of MetaPost and its corresponding m-
graph ConTeXt module this week. I've been getting very attractive results
that I will encourage my partner to use in her PhD.

I was baffled for a while why I could get graphing to work beautifully in
one directory, but in no others. I finally tracked it down to the system
requiring texnum.mpx in the current working directory. I believe this
file contains the MP-ified numbers that MPGraph puts on the axes. 

My question is: why should this be? I *think* I have done everything else
necessary to get MP working in ConTeXt. How can I automatically generate
texnum.mpx in a way that 1) another user doesn't have to worry about it
or 2) it sits in the path permanently?


Some system details: I'm running a fresh TeXLive 7 install, with the
latest ConTeXt from the website. I have \write18 enabled,
\runMPfraphicstrue, \runMPTEXgraphicstrue, and MPXCOMMAND = texexec --
mptex. On the slightly unusual side, I have \forceMPTEXgraphictrue, which
seemed necessary at one point, and no \recycleMPslotstrue, which seemed
unnecessary.

I'm thrilled with the integration of MetaPost's Graph capabilities,
beyond this strange behaviour that took a long time to track down. It was
very easy to get very attractive results from simple data files.


As a side question, would I have to fiddle with texmf/metapost/base/
texnum.mp to affect the font of the x- and y-axis numbers on an MPGraph
plot? They seem to stick to CMR no matter what I do to defaultfont in
MetaPost.

Thanks,
adam
