Hello, I just started experimenting with pgfplots package.
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! Sorry, I could not read the plot coordinates near
'(5,15)(20,20)(24,-24)'. Please check for format mistakes.
! Package pgfplots Warning: the current plot has no coordinates (or all have
been filtered away)...
"
Any idea from someone more familiar with pgfplots would be appreciated.
TIA.
Best regards,
Lukas
