Dear Hans, mathams.tex defines \triangledown, but for symmetry it should imhoalso define \triangleup: \definemathsymbol [triangleup] [ord] [ma] ["4D] The symbol is currently only defined as \vartriangle, but that is a relation. regards, Christopher Creutzig

ok, done, but it's the sams as vartriangle (i suppose that math guru's know the difference in usage ) Hans  Hans Hagen  PRAGMA ADE Ridderstraat 27  8061 GH Hasselt  The Netherlands tel: 038 477 53 69  fax: 038 477 53 74  www.pragmaade.com  www.pragmapod.nl

The spacing around it is different, ord vs. rel. Those who don't see the difference may not deserve it. :) regards, Christopher Creutzig
Hello all, I need to typeset a few (simple) diagrams in ConTeXt, like the ones mathematicians use, with arrows. In LaTeX, one can use pictex or DCpic. The latter claims also to work with ConTeXt, but I couldn't find an example. Has anybody managed to do something like this? (essentially, I only need something like Math Text > Math Text > Math Text          v v v Math Text > Math Text > Math Text sometimes also with diagonal arrows). Thanks

Without diagonal arrows you could use the flow charts module. Grüßlis vom Hraban!  http://www.fiee.net/texnique/
Thanks  while it looks really nice, I do need diagonal arrows. However, after some experimenting, I catually managed to get DCpic to work. It is just a plain TeX file, I was only scared by the .sty name. If somebody else runs into the same problem, here is a short example, for reference. You will need dcpic.sty in your path first. Then one can create diagrams as follows: \usemodule[pictexwd] \input dcpic.sty \starttext \begindc{\commdiag} \obj(1,2){$V_i$} \obj(3,1){$V'$} \obj(3,3){$V$} \mor{$V_i$}{$V$}{$f_i$} \mor{$V_i$}{$V'$}{$f_i'$}[1,0] \mor{$V$}{$V'$}{$f$} \enddc \stoptext Matthias On Sep 29, 2004, at 3:07 PM, Henning Hraban Ramm wrote:

Why not use MetaPost? With all of ConTeXt's features for doing indocument MetaPost code, this would be the perfect solution for your problem. Have a look at Hans's MetaFUN manual for a good starting point on using it. Also, I believe the original MetaPost manual has some examples of figures very much like the ones that you want to draw.

Hi, although you already have solved your problem, I encourage you to have a look at the metaobj package for metapost. The 'PSTricks/METAOBJ gallery' part of the manual (p. 93ff) shows some diagrams you will surely like. Greetings,  Eckhart
