This is indeed a problem, since metapost only sees one btex/etex here and
not obe for every loop.
This is why in context you can use the textext macro:
beginfig(1) ;
numeric u ; u = 1.0cm ;
for i=-10 upto 10 :
if not (i=0) :
draw textext.lft("$" & decimal i & "$") shifted (i*u,0) ;
fi ;
endfor;
endfig ;
end
given that you have configured texexec well:
texexec --mptex thisfile.mp
mptopdf thisfile.1
will give you a nice axis (beware if you look into gs: mptopdf does not
overwrite an open file).
[there are a few more text related tricks; also, i'm working on a module
for drawing axis etc]
