Dear Luigi,
Thanks you very much. On my computer, the provided test.mp seems still not to work:
The output with numbersystem=decimal is attached (test-1-decimal.mps); the y-axis is still wrong.
The usual output is test-1.mps; the y-axis labelling is correct (includes negative values).
My point is not this particular example, because I do not need this particular code (by introducing your very good hack). But still, thank you very much for your good help!
My point is: It seems that the graph-macros were not tested with the new numbersystems, and because you or Taco Hoekwater have introduced the new numbersystems, it would be nice to have a short comment on this how to proceed regarding the new numbersystems and the graph-macro.
Best regards,
Martin

This should be ok
% 0 1.4
% 1 3.2
% 2 -4.5
% 3 8.0
% 4 9.0
% 5 4.0
% Data-file for graph can be included at beginning of source-file,
% because %<space>0 1.4 etc. is read by gdata marco until empty line
input graph
prologues := 3;
outputtemplate := "%j-%c.mps";
if numbersystem="decimal":
%% numberprecision:=6;
vardef Mabs primary x = x/10*10 enddef;
fi
beginfig(1)
draw begingraph(10cm,10cm);
path p;
gdata("test.mp<http://test.mp>", $, augment.p(i, scantokens $2););
gdraw p;
endgraph;
endfig;
end
