[NTG-context] Add labels to a grid (Metafun)

2015-03-06 Thread Fabrice Couvreur 
To add labels to a grid, Hans wrote a macro hlintext (Min, Max, Step, Lenght
, Format). I do not know what to put in Format.
Best regards,
Fabrice

\definecolor[mycolor][c=.4,m=0,y=0,k=0]
\starttext
\start
\switchtobodyfont[small]
\startMPcode
 input tex;
 numeric xmin, xmax, ymin, ymax;
 xmin := 0; xmax := 22; ymax :=460 ;ymin:=0; u := 0.5cm; v:= 0.025cm;
 drawoptions(withpen pencircle scaled 0.5pt withcolor
\MPcolor{mycolor});
 draw hlingrid(ymin,ymax,20,11.5cm,11cm);
 draw vlingrid(xmin,xmax,2,11cm,11.5cm);
 drawoptions(withpen pencircle scaled 1pt) ;
 drawarrow (0,0)--(22,0) scaled u ;
 drawarrow (0,0)--(0,460) scaled v ;
 for i=0 step 2 until 20 :
label.bot(TEX($decimal(i)$),(i,0)*u);
 endfor;
 for i=0 step 20 until 440:
label.lft(TEX($decimal(i)$),(0,i)*v);
  endfor;
 label.bot( $x$,(10.8cm,-0.1cm)) ;
 label.rt( $y$,(0.1cm,11.3cm)) ;

thank you very much Alain, I think I understood for the format @d but 
for other formats, I will need documentation.

it is a string format specifier such as %g, %f, %d, ...
Since the % can sometimes cause problems being interpreted as a comment
character, it is usually replaced in Metafun by @, as in @g.
