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?

For the record, I'm not actually trying to "show" the picture that is
returned by the format() function, but instead I want to assign the
value of this picture to a variable, and it is erroring with that as
well.

Sorry for the flood. After some digging around it seems like the %
should now be replaced by @. That is, I should use
format("@g",n)

Is the sarith package usable in MKIV? For example, I would like to
get the numerical (not string) values of auto.x and auto.y from the
graph package. I expect the following example to work, but it does
not (even if I "input sarith") with MPinclusions.
\usemodule[graph]
\ctxlua{metapost.showlog=true}
\startMPpage
draw begingraph(1in,1in);
setrange((0,0),(1,1));
for n=auto.x:
show Scvnum n; % This is the line that is failing
endfor;
endgraph;
\stopMPpage

This works:
\startMPinclusions
input graph;
input sarith;
\stopMPinclusions
Apparently, an explicit input graph is needed as well. I have no idea
why though, as there is an \startMPinclusions inside m-graph.mkiv too.
Best wishes,
Taco

\startMPinclusions[+]
input sarith;
\stopMPinclusions

This probably explains other problems that I had experienced
concerning \startMPinclusions\stopMPinclusions...
Indeed, as metapost is processed in one run under mkIV,
I had gotten around such problems by simply putting certain metapost
definitions in an early instance of \startMPcode\stopMPcode.
Perhaps the [+] option could/should be by default for MPinclusions
with some other option syntax allowing one to reinitialize
the MPinclusions. Or maybe not...
In any case, we need to document this more clearly.
Concerning the graph package:
1) Should it use \startMPinclusions[+] so as not to erase
other MPinclusions?
2) Is there a penalty/overhead in including sarith by default
in the graph package?
3) Will metapost be able to better handle arithmetic soon,
and/or can someone suggest a better way of using lua along
with metapost graph? (Currently I externally use "awk"
via \immediate\write18 to manipulate data.)

In mkiv you should be able to manipulate your data with lua & lpeg.
You gain in portability -- no need of an external awk

Yes, another language to learn... (after all, I *like* awk)
Can you indicate a good starting point?
(perhaps this message should be filed under the thread on documentation...)
