Hello,
one more question about pgfplots & Lua:
how to specify "reverse legend" by Lua?
Here are some examples:
- Plot 1 contains no Lua code and gives the desired result (OK);
- Plot 2 uses Lua to specify "legend entries" successfully (OK);
- Plot 3 tries to use Lua to specify "reverese legend", but doesn't work;
----
\usemodule[pgfplots]
\starttext
Plot 1 -- OK
\starttikzpicture
\startaxis[legend entries={Cos,Sin2,Sin},reverse legend]
\addplot+[mark=none,fill,green]{cos(deg(x))}\closedcycle;
\addplot+[mark=none,fill,yellow]{0.5*sin(deg(0.5*x))}\closedcycle;
\addplot+[mark=none,]{sin(deg(x))}\closedcycle;
\stopaxis
\stoptikzpicture
Plot 2 -- Legend by Lua -- OK
\starttikzpicture
%\startaxis[legend entries={Cos,Sin2,Sin}]
\cldcommand{startaxis{["legend entries"] = "{Cos,Sin2,Sin}"}}
\addplot+[mark=none,fill,green]{cos(deg(x))}\closedcycle;
\addplot+[mark=none,fill,yellow]{0.5*sin(deg(0.5*x))}\closedcycle;
\addplot+[mark=none,]{sin(deg(x))}\closedcycle;
\stopaxis
\stoptikzpicture
Plot 3 -- Reverse legend by Lua -- not working
\starttikzpicture
%\startaxis[legend entries={Cos,Sin2,Sin},reverse legend]
\cldcommand{startaxis{["legend entries"] = "{Cos,Sin2,Sin}", "reverse legend"}}
\addplot+[mark=none,fill,green]{cos(deg(x))}\closedcycle;
\addplot+[mark=none,fill,yellow]{0.5*sin(deg(0.5*x))}\closedcycle;
\addplot+[mark=none,]{sin(deg(x))}\closedcycle;
\stopaxis
\stoptikzpicture
\stoptext
----
So how to make Plot 3 work?
Best regards,
Lukas

This is not valid lua. On a lua prompt, try
t = {["legend entries"]="{Cos,Sin2,Sin}", "reverse legend"}
you get
stdin:1: table index is nil
stack traceback:
stdin:1: in main chunk
[C]: in ?
One can define a lua table using
{[key]=value, [key]=value, ... } etc
or
{value1, value2, ...} etc.
Mixing the two is not allowed.
In ConTeXt, the two are not mixed. But tikz (and pgfplot) freely mix the
two syntax. So, one way to get the result using lua is (untested)
\ctxlua{"\\startaxis[legend entries={Cos,Sin2,Sin}, reverse legend]"}
where, if needed, you can build the string using string.format.

such a table is valid lua (mixture of indexed and hashed) but of course
the application using it has to know how to use it

You are right. Sorry for the noise.

Hello,

OK, so when '{["legend entries"]="{Cos,Sin2,Sin}", "reverse legend"}' is a valid Lua call and, what I guess, a valid Lua-to-context call -
- why the code doesn't work?
I also tried Aditya's way II - to build the "command-string" and to pass it to context:
"
context(string.format("\\startaxis[legend entries={%s},reverse legend]", "Sin,Cos"))
"
It works, although I'd rather use "context.startaxis{...options...}" style as it looks "nicer".
Next question - why
"
context[[\startaxis]]
"
doesn't work, whilst
context"\\startaxis"
does?
(See attached files.)
Best regards,
Lukas
