This code compiles fine with plain MetaPost.
input graph;
beginfig(0);
draw begingraph(1in,1in);
setrange((0,0),(1,1));
for n=auto.x:
show format("%g",n);
endfor;
endgraph;
endfig;
end
However, this "ConTeXt translated" version errors in MKIV
\usemodule[graph]
\ctxlua{metapost.showlog=true}
\startMPpage
draw begingraph(1in,1in);
setrange((0,0),(1,1));
for n=auto.x:
show format("%g",n);
endfor;
endgraph;
\stopMPpage
See foo.log (attached).
Thoughts?
