I was aware of this solution; however, I was looking for another way due to performance reason and to avoid having too many temporary (data) files.
\addplot table {<file.data>};
That will work.
It seems I found a more Lua way:
----
\usemodule[pgfplots]
\startluacode
data = {{5, 15}, {20, 20}, {24, -24}}
data2crds = function(data)
local str
for i, v in ipairs(data) do
str = (str or "") .. "(" .. v[1] .. "," .. v[2] .. ")"
end
print("Crds=", str)
return str
end
--
plot = function(data)
context.starttikzpicture()
context.startaxis{}
context.addplot{mark="none",color="red"}
context("coordinates {" .. data2crds(data) .. "};")
context.stopaxis()
context.stoptikzpicture()
end
\stopluacode
\starttext
\starttikzpicture
\startaxis[]
\addplot[mark=none,color=red] coordinates {(11, 5) (12, 18)};
\stopaxis
\stoptikzpicture
\ctxlua{plot(data)}
\stoptext

Anyway, thanks.
Best regards,
