Hello,
Is it possible to calculate the position of something in Metapost, and
to export that value to TeX such that I can use it in setups and
things?
I thought perhaps I could \def inside btex..etex. Here's a minimal
example trying to illustrate the idea:
\startuniqueMPgraphic{canon}
path
;
label.bot(btex $x$ etex,(2.97u,-0.1v)) ;
label.rt(btex $y$ etex,(0.01u,3.9v)) ;
label.llft(0,(0,0)) ;
label.urt(A,(0,v)) ;
dotlabel(,(u,-4v)) ;
label.rt(C,(1.02u,-4v)) ;
dotlabel.lrt(B,(2u,3v)) ;
label.bot(1,(u,0)) ;
label.lft(1,(0,v)) ;
clip
)--(0,4v) ;
draw curvedfunction (x, 3*x*x-5*x+1, -1, 3, 0.01) xyscaled (u,v)
withcolor red ;
draw curvedfunction (x, -5*x+1, -1, 3, 0.01) xyscaled (u,v)
withcolor blue ;
draw curvedfunction (x, 7*x-11, -1, 3, 0.01) xyscaled (u,v)
withcolor green ;
label.bot(btex $x$ etex,(2.97u,-0.1v
);
for i=0 step 10 until 100:
label.bot(TEX($decimal(i)$),(i*u,0));
endfor;
for i=0 step 1000 until 7000:
label.lft(TEX($decimal(i)$),(0,i*v));
endfor;
label.top(Nombre de lots,(90u,50v));
label.lrt(btex $f(x)$ (en euros) etex,(0,7800v));
\stopMPcode
\stop
);
for i=0 step 10 until 100:
label.bot(TEX($decimal(i)$),(i*u,0));
endfor;
for i=0 step 1000 until 7000:
label.lft(TEX($decimal(i)$),(0,i*v));
endfor;
label.top(Nombre de lots,(90u,50v));
label.lrt(btex $f(x)$ (en euros) etex,(0,7800v));
\stopMPcode
\stop

label.lrt(btex $f(x)$ (en euros) etex,(0,7800v));

what is:
input hvdm;
input tex;
both names are also candidates for name clashes

Note that in MkIV, this can be shortened to
label(Cn, origin) withcolor white;
No need to wrap the strings around \sometxt{...} or btex ... etex.

How about something like below
like in
the code below.
