I'd have two questions: 1) When plotting/loading a data file: Is it possible to specify the comment mark, which is '#' and '%" by default? I'd need to treat ';' as a comment mark, too. 2) How to pass coordinates of plot points by Lua? The following code: ---- \usemodule[tikz] \usemodule[pgfplots] \startluacode data = {{5, 15}, {20, 20}, {24, -24}} plot = function(data) local str for i, v in ipairs(data) do str = (str or "") .. "(" .. v[1] .. "," .. v[2] .. ")" end print("Crds=", str) context(str) end \stopluacode \starttext \starttikzpicture \startaxis[] \addplot[mark=none,color=red] coordinates {(11, 5) (12, 18)}; % THIS PLOT IS OK \addplot[mark=none,color=red] coordinates {\ctxlua{plot(data)}}; % THIS PLOT HAS NO POINT (?!) \stopaxis \stoptikzpicture \stoptext ---- gives error: " ... fonts > fallback modern rm 12pt is loaded Crds= (5,15)(20,20)(24,-24) Package pgfplots: Error!

As far as I know \addplot scans the coordinates in a way that a macro is not possible here . However, write your coodinates into an external file and read it with \addplot table {<file.data>}; That will work.
