Maybe something has changed to graph.mp (esp the trigger for reloading it),

in mp-form add a line at the top:

   boolean mant_font ; mant_font := true ;

this will prevent loading form.mp (which is replaced by a sligthly extended 
version mp-form) and therefore loading of texnum

Also in your graphic: use the simpler \startMPcode ... \stopMPcode and not 
the low level macros; also saves keying.

if you have the *.d files and m-graph.tex on the same path, you can run

   texexec --mode=demo --pdf m-graph

to get a test file

Hi Hans.

I believe Hans Hagen said this around Wed, 30 Oct 2002:

I did that as instructed, (and remade metafun (oops, didn't do that at
first) in the right place (oops again)), and it was successful.

Thanks! That solves the big issue.

It'll take me a bit longer to figure out how to use init_numbers so that
I can have the axis numbering be in the font I want (expecially because
it depends on the math font). My initial experiment with the following
ugly hack didn't work:

 init_numbers(btex$-$etex, btex{\ss 1}etex, btex${\times}${\ss 10}etex,
  btex${}^-$etex, btex${}^2$etex);

>Also in your graphic: use the simpler \startMPcode ... \stopMPcode and not

Ah, right. I had only skimmed through the metafun docs, and didn't notice
that simpler approach while I was reading chapter 3: Embedded graphics.
Keying isn't a big concern as I'm planning on wrapping those calls into
macros of some sort, but it helps to use the "right" command.

Yup. That's how I got started.
And if other people want to find those *.d files, take a look in:
 texmf/doc/metapost/base/


Many thanks,
adam

actually, this si not used at all, when enables, context/metafun will use 
"textext" which follows the document settings

Following this thread and making the modifications suggested by Hans I had
expected the following metapost graph to work but there is a problem with
fonts. Even though in context cont-sys.tex is executed giving ec as the
default encoding in the metapost case it has defaulted to 8t in the encoding
extension. I tried 
\unprotect
\setupencoding [\s!default=ec]
\protect
Before \setupbodyfont with no effect

-----begin mp file
input metafun ;

verbatimtex
\setupbodyfont[pos,12pt]
\starttext
etex
input graph;

prologues:=2;


beginfig(1);
draw begingraph(2in,2in);
setrange(80,0, 90,180);
autogrid(otick.bot,otick.lft);
endgraph;
endfig;

verbatimtex
\stoptext
etex

end
-----end mp file

\startMPenvironment
\setupencoding[default=ec]
etc etc
\stopMPenvironment

is the way to go

Thanks Hans I think that you may have missed the point. I was wanting to
arrange the fonts in the metapost output from a metapost file to be from the
pos set. The file below is a minimum one which works nicely showing times,
helvetica, and courier fonts.

New Berry problem.
One of the problems that made this more difficult to fault find was that the
berry (ec) encoding seems to have stopped working properly in the 23/10/2002
release. I have had to change to texnansi to get my previous files to
compile properly.

Hmm, maybe i miss here something, but 8t is ec-encoding, isn't it?

default= means: use this encoding if no encoding is specified for the
font
Does \usetypescript[berry][ec] help?

replacing

     [default=texnansi]
With
 \usetypescript[berry][ec]
Causes the error again the start of which is shown below

this is since there is no utmr8t.tfm on your system. Older TeX systems
had (IMO) wrong tfm file names like ptmr8t.tfm for Times in T1
encoding. The problem is that the "p" means the font-vendor is Adobe,
but all font setups have used fonts from URW. Thus the "p" is wrong
and has been replaced with the appropriate "u" for URW in modern TeX
systems, for example in TeXLive. ConTeXt is correctly configured to
use these URW font names. The best solution is to install a TeX
system that provides these font names.

Thanks for this, utmr8t.tfm is indeed not on my system at work which is
older. I have just installed Gerben's i-installed TeX-fat.dmg on my home
machine. It will be interesting to see what is there. I mistakenly thought
that I was expecting 8a on the end for ec encoding. I do have ec-utmr8a.tfm
manufactured by texfont by type-tmf.dat dated 11/9/01 even thought the
overall context is 23/10/02. Appropriate lines duplicated below.

# urw times 

--en=? --ve=urw --co=times --so=auto
--en=? --ve=urw --co=times --so=auto --ca=* utmr8a
--en=? --ve=urw --co=times --so=auto --sl=* utmr8a

8a means the original encoding of the AFMs. texfont takes this basename and
precedes this with a ec- for a T1 (ec) encoded font. This is the ConTeXt/texfont
naming scheme. If you stick to the Berry naming scheme then this font will
be 8t in T1 encoding, 7t in OT1 and there are some more, see fontinst.[dvi|ps|pdf]
on CTAN. Normally the T1 encoded fonts are already on your system due to
the LaTeX PSNFSS (PostScript New Font Selection Scheme) has already installed it.
Thus you don't need to install them again using texfont, the only thing to do is
to tell ConTeXt that the Berry fontnames have to be used. This is exactly what
\usetypescript[berry][ec] does.
