Hi,

I'd like to use graph to draw my plots with metapost. However, the
following minimal file does not work:

\usemodule[graph]
> \starttext
> \startMPcode
>   draw begingraph(3in,2in);
>     gdraw "agepop91.d";
>   endgraph;
> \stopMPcode
> \stoptext


The complete output log is available here: http://pastebin.com/zuGaT87W

Thank you for your help !

I can generate the proper picture by writing only metapost code such as :

input graph
> beginfig(0);
> draw begingraph(3in,2in);
>   gdraw "agepop91.d";
> endgraph;
> endfig;
> end;
