By default, pgfplotstable breaks lines at white space (tab or space
according to the pgfplotstable manual). I used tabs as column separators
in my demo file. With MKiV, the columns are correctly split but with
LMTX, pgfplotstable sees a single column.
I explicitly stated that the columns are separated with tabs:
\addplot table [x=t, y=E, col sep=tab] {mfe-addplot.dat};
and it works. I tried to change the columns separator to a space,
instead of a tab and it also works.
I don't know what pgfplotstable uses to split columns, but the
conclusion is that with MkIV 'col sep=space' means space or tab, whereas
with LMTX it means strictly a space character.
Thank you very much for your help.
I think I have it running now but you have to wait for an update (one of
those curious border cases where tex bends a rule by turning tabs into
spaces (the alternative is to let the tab token flagged as spacer travel
around which would permits round trip). Makes me wonder I should have
that as option in luametatex (but as I'm now in metapost mode I delay
that pondering.)
