Hi,
I am back to trying Metapost. I spent sometime yesterday and today
learning about clipping, buildcycles etc. to fill areas with patterns.
I think I will try to write a simple tutorial with it.
Meanwhile, I just updated my installation of Context minimals. The
following simple Metapost code does not compile with MKIV, but
compiles okay with MKII.
\setuppapersize[letter][letter]
\setupcolors[state=start]
\setuppagenumbering[state=stop]
\starttext
\startuseMPgraphic{Filling}
u := 1cm;
w:= 2pt;
%Axes
path xaxis; path yaxis;
xaxis := (0,0)--(12,0) scaled u;
yaxis := (0,0)--(0,12) scaled u;
path demand; path AC;
demand :=
function (1,"x","10-x",0,10,1) scaled u;
AC :=
function(1,"x","2+8/x",1,10,0.1) scaled u;
drawarrow xaxis withpen pencircle scaled w;
drawarrow yaxis withpen pencircle scaled w;
draw demand withpen pencircle scaled w withcolor 0.5red;
draw AC withpen pencircle scaled w withcolor 0.5green;
fill fullcircle scaled u shifted (4*u,5*u) withcolor 0.1[white,blue] ;
label(btex \tfb S1 etex,(4,5)*u);
\stopuseMPgraphic
\midaligned{\useMPgraphic{Filling}}
