Dear Hans
Thanks for your quick answer! I was however not able to produce the graph with the textext code... Should I actually then use another compiler? I tried with context and texexec (I thought texexec is the compiler for mkiv, right? I'm on linux ubuntu).
no, use the 'context' command as texexec is for mkii
ok, so I was using the right compiler.... I get a mystake while trying to compile a file with the code you sent... you didn't? Would you be so nice and send complete file, so I can check what is wrong?
I saw also that, as you mention, context has a \frac: http://wiki.contextgarden.net/Math_with_newmat
indeed, \frac is already there for a long time (ams compatible command)
btw, in mkiv there is no m-newmath
I tried then to simply add \usemodule[newmat] and compile with context, but did not work... Code below, error message below below... ! Math error: parameter \Umathfraction_del_size\displaystyle is not set. l.3 ...t{411}{$\displaystyle \frac {\sigma _t}{a}$ } <inserted text> ...ore.mp ; fi ; ;;;]===], false)}
make sure that a font is loaded that has math before \starttext is seen
(try with \setupbodyfont[palatino] at the top of your file)
this does not work neither.... I still get error message with this code:
\usemodule[newmat]
\setupbodyfont[palatino]
\starttext
\startMPpage
label.top(textext("$ \frac{\sigma_t}{a}$") scaled 1.00, (1, 1));
%label.top(btex $ \frac{\sigma_t}{a}$ etex, (0, 10));
%label.top(textext( $\displaystyle \frac{\sigma_t}{a}$ ) scaled 1.00, (1, 1));
\stopMPpage
\stoptext
Hi, this works for me. \setupbodyfont[palatino] \startMPpage[offset=1ex] u := cm ; label.top(textext("$ \frac{\sigma_t}{a}$") scaled 2, origin); label.top(textext("$ \frac{\sigma_t}{a}$"), (u,u)); label.top(textext("$\dfrac{\sigma_t}{a}$") scaled .5, (u,0)); \stopMPpage Greeting Andreas
