Just testing

[Pierre Goossens]

Hello everyone,

On January 15th at 23:31 I posted a message to ntg-context@ntg.nl

Since that time I received messages from the mailinglist but I haven't seen
the one I submitted. I didn't get a reply from my postmaster so I looks
like it is on its way. But because of the long wait I decided to try it
with this one (January 17th, 17:35). Let's see....

With regards,

Pierre Goossens

Labeling of axes

[walter kehowski]

ConTeXtnicians,

This is a MetaPost question, not a ConTeXt question, per se. Does anybody know
how to use a for loop to label axes and, secondly, how to pass paramters to a
metapost file?

For example,

numeric u; u=1.0cm;
for i=-10 upto 10:
if not(i=0) lablel.lft(btex $i$ etex, (i,0)*u); fi;
endfor;

does not work. Any suggestions?

Thanks,

Walter Kehowski

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]

That is a really great feature!  I've been missing an easy way to
interpolate data into tex-typeset labels.

An additional thing i've done [already long ago but time flies by] is to
patch some of hobbies modules so that when needed this method is used
instead of the kind of pseudo typesetting that takes place in the diagram
modules. Interesting code in itself, this code of hobby, since it assembles
numbers from snippets of btex/etex pictues, but unfortunately it invokes
too many additional runs.

Hi Hans,

When I try this, I get an error (see end of mail).
When I run this with plain mpost the labels
are all of the form ``unknown''. Am I doing
something wrong?

Thanks in advance.

Marc

This means that no tex is run.

Looks like your cont-new file is out of sync with the rest of context
[actuall you seem to use a new cont-new.tex and an older context]. When i
patch context with new features, keywords may be added, in this case \??ks
is a namespace thing. Therefore all files should be in sync [at least with
new features].

Neither, for the moment an inconvenience which i will cover later. Just
load the file in advance: 

\useJSscripts[fil,fld]

somewhere at the beginning.

  With ConTeXt 2003.8.15, I get (\000) in thisfile.1, which mptopdf does
not handle:

! Undefined control sequence.
l.14 (\0
         00) cmsy10 11.95514 fshow

These seem to be the minus signs.
