Thank you again, but the "0.0" remains unchanged. The only way I've been
able to succeed is with a for loop to label explicitly. See mwe below for
things I've attempted. The last two for lines seems to be what it takes
(with the other Auto lines commented out of course.)
% 0 0
% 1 1
% 2 3
% 3 5
\enabletrackers[metapost.showlog]
\usemodule[m-graph]
\startMPpage[instance=graph, offset=5mm]
draw begingraph(160, 100);
gdraw "mwe-2.tex" plot circles(0);
Autoform := "@0.g" ;
autogrid(otick.bot,otick.lft);
% for x=auto.x: otick.bot(format("@g",x),x); endfor;
% for y=auto.y: otick.lft(format("@g",y),y); endfor;
% for x = 0 upto 3: otick.bot(x,x); endfor;
% for y = 0 upto 5: otick.lft(y,y); endfor;
endgraph;
\stopMPpage
