Dear Mikael,

An example from PGFPlots Gallery. Please try if it works. Here on windows, it seems to work. Attached files are tt.log.txt and tt.pdf.

Best, Akira

it's ok with TL 2014 (and the latest luatex from experimental), that has \def\pgfversion{3.0.0} and it should be the http://sourceforge.net/projects/pgf/ but downloading the pgf module from the garden lua error > error on line 75 in file /opt/luatex/standalone-mkiv-new-I/tex/texmf/tex/generic/pgf/libraries/luamath/pgflibraryluamath.code.tex: ...iv-new-I/tex/texmf-context/tex/context/base/util-lib.lua:246: module 'pgfluamath.functions' not found: no field package.preload['pgfluamath.functions'] no file '/usr/local/share/lua/5.2/pgfluamath/functions.lua' no file '/usr/local/share/lua/5.2/pgfluamath/functions/init.lua' no file '/usr/local/lib/lua/5.2/pgfluamath/functions.lua' no file '/usr/local/lib/lua/5.2/pgfluamath/functions/init.lua' no file './pgfluamath/functions.lua' no file '/usr/local/lib/lua/5.2/pgfluamath/functions.so' no file '/usr/local/lib/lua/5.2/loadall.so' no file './pgfluamath/functions.so' no file '/usr/local/lib/lua/5.2/pgfluamath.so' no file '/usr/local/lib/lua/5.2/loadall.so' no file './pgfluamath.so' stack traceback: [C]: in function 'savedrequire' ...iv-new-I/tex/texmf-context/tex/context/base/util-lib.lua:246: in function 'require' [\directlua]:1: in main chunk 65 \let\pgfutil@directlua\directlua 66 \pgfutil@directlua{% 67 tex.enableprimitives('pgfutil@',{'luaescapestring'})} 68 \else 69 \def\pgfutil@directlua#1{} 70 \def\pgfutil@luaescapestring#1{} 71 \fi 72 73 \pgfutil@directlua{% 74 pgfluamathfunctions = require("pgfluamath.functions") 75 >> pgfluamathparser = require("pgfluamath.parser")} 76 77 78 % Patch some configuration macros such that the modifications are 79 % available in LUA as well: 80 \pgfkeys{ 81 /pgf/trig format/deg/.add code={}{\directlua{pgfluamathfunctions.setTrigFormat("deg")}\aftergroup\pgfmath@settrigformat }, 82 /pgf/trig format/rad/.add code={}{\directlua{pgfluamathfunctions.setTrigFormat("rad")}\aftergroup\pgfmath@settrigformat }, 83 } 84 % ... and reactivate the key: 85 \pgfmathiftrigonometricusesdeg{% and \def\pgfversion{3.0.0-cvs} So it seems that the cvs version is not ok with ctx and I think that these 74 pgfluamathfunctions = require("pgfluamath.functions") 75 >> pgfluamathparser = require("pgfluamath.parser")} are also wrong in Lua . -- luigi
