Add labels to a grid (Metafun)
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)) ; \stopMPcode \stop \stoptext

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