mpgraph does not appear to work properly under mkiv.
%% minimal example %%
\starttext
\startuseMPgraphic{test}
input graph
draw begingraph(16cm,12cm);
setrange(whatever,whatever,whatever,whatever);
gdraw (0,0) -- (1,1) ;
endgraph;
\stopuseMPgraphic
\startTEXpage
\useMPgraphic{test}
\stopTEXpage
\stoptext
%%%%%%%%%%%%%%%%%%%%%
Works correctly under mkii (texexec) but not under mkiv (context).
