Hello Alexander,
I don't understand your problem, but perhaps you should write the psplot
command inside a \pspicture(0,-1)(1,1) ... \endpspicture.
Cheers, Peter

 


This works for me (I suppose your code is in pstest-texapp.tex):
$> texexec --output=dvips pstest-texapp.tex
$> dvips -o pstest-texapp.ps pstest-texapp.dvi
$> ps2pdf14 pstest-texapp.ps

[NTG-context] Re: function plotting

2005-10-04 Thread David Arnold 

Alexander,

There is a lot of plots you can do with Metapost. Ordinary, every day  
stuff. For example:


beginfig(1);

% initialize a and c for f(x)=|x-a| and g(x)=c
numeric a, c;
a=-2;
c=2;

% initialize function label abcissas and postions
numeric flabel, glabel;
flabel:=-5;
glabel:=-5;

% define function f(x)=|x-a|
vardef f(expr x)=
abs(x-a)
enddef;

% draw line with given point and slope
path F;
F:=(-5,f(-5));
for x=-5 step 1 until 5:
F:=F--(x,f(x));
endfor;

% initialize scale
numeric u; 10u=4cm;

% the line
F:=F scaled 1u;
draw F withcolor blue;

% clipping path
path cpath;
cpath:=(-5,-5)--(5,-5)--(5,5)--(-5,5)--cycle;
cpath:=cpath scaled 1u;

% clip and save current picture
picture pic;
clip currentpicture to cpath;
pic:=currentpicture;

% erase currentpicture
currentpicture:=nullpicture;

% draw grid
for k=-5u step 1u until 5u:
draw (-5u,k)--(5u,k) withcolor 0.85white;
draw (k,-5u)--(k,5u) withcolor 0.85white;
endfor;

% draw axes
drawarrow (-5u,0)--(5u,0);
drawarrow (0,-5u)--(0,5u);

% label axes
label.rt(btex $x$ etex, (5.2u,0));
label.top(btex $y$ etex, (0,5.2.u));
label.bot(btex $5$ etex, (5u,0));
label.lft(btex $5$ etex, (0,5u));

% redraw line
draw pic;

% label the functions f(x)=|x-a| and g(x)=c
pair D, E;
D:=(-5,f(-5)) scaled u;
label.lft(btex $f$ etex,D);
E:=(-5,2) scaled u;
label.lft(btex $g$ etex, E);

% draw the graph of g(x)=c
path G;
G:=(-5,2)--(5,2);
G:=G scaled u;
draw G withcolor blue;

endfig;

end.

And for a good stats package, see:

http://www-math.univ-poitiers.fr/~phan/statsmac.html

And for good circuits diagrams, see:

http://www.cnm.es/~pserra/schema/whatis.html

Don't give up on Metapost too soon. It's an awesome language and the  
file size created are small, a plus when you're document includes  
lots of figures and you want it to download in reasonable time on the  
internet.

 Since afaik ConTeXt does not have an equivalent of LaTeX's picture
environment, I don't see much point in teaching gnuplot some sort of
ConTeXt output.  I'm no gnuplot expert, but my guess is that tweaking
the metapost prologues and some minor code tweaks would probably be the
easiest way to go.

[NTG-context] Bib-module: crossreferences

2005-10-04 Thread Roelof Langman 
Hi Taco,

Are crossreferences supposed to work in the new bib module? According to the
Latex companion pp. 404ff. a crossreference can be made in an @inbook to a
@book provided the @inbook precedes the @book in a .bib-file. If a @book is
referenced at least two times by an @inbook, an entry for the @book is
included in the reference list. 

In the new bibtex-module for Context, the crossreferences are resolved
properly, I think, but the crossreferenced entry is not yet included in the
reference list.

I \cite[gould:1979] and \cite[rioch:1979], but lawrence:1979 doesn't appear
in the reference list.

Cheers, Roelof

@inbook{gould:1979,
  author = "Gould, Laurence J.",
  crossref = "lawrence:1979",
  title = "Men and Women at Work: A Group Relations Conference on Person and
Role",
  note = "See also \cite[rioch:1979].",
  pages = "111--122"   }

I use gnuplot which makes graphs of superb visual quality and has
extensive support for many different function manipulations and weird
stuff that you want to do with it. I do something like:

set terminal latex
set output "file.tex"
set title '\bf My wonderful function $sin(\omega t)$'
set xlabel '$t\ \rm[s]$'
set ylabel '$A$'
plot sin(x)

and then "\input file" inside of the main LaTeX file. Gnuplot cannot
make output in ConTeXt (yet), but perhaps you can include the

 Not really, that causes all sorts of problems when trying to get the

 But you might be interested (assuming you can read or at least decipher

[NTG-context] ISO Latin 2 input under the new ConTeXt

2005-10-04 Thread Michal Kvasnička 

Good evening.

Many thanks to all of you that helped me to install teTeX 3.0. I found 
that I can really use SuSE 9.3 rpms under my SuSE 9.2, which quite 
surprised me. (I can't use Mr. Hagen's minimumdistribution, because 
there is no MetaFont in it, and I still use some bitmapped fonts, e.g. 
Concrete Math).


Now I have to solve the last (I hope so) problem: The Czech encoding. I 
have all my input files in ISO Latin 2 encoding. It was no problem up to 
now because I used fonts with IL2 encoding. What shoud I do now the new 
LM fonts?


(BTW, is it all right that I have to include
   \loadmapfile[psclean.map]
in all my documents? LM fonts are not preloaded, and I can't find in 
teTeX 3.0 pdftex.conf to include it.)


(In the last two years I missed all font-related changes in ConTeXt. 
What manuals should I read to understand how to use ConTeXt properly?)


With many thanks
Michal Kvasnicka

P.S. And by the way, in the future I may need to switch all my inputs 
into UTF8. How can I typeset files like that in the ConTeXt? Many thanks.
