I'd like to plot some measured values with TikZ, but despite "calling" LuaLaTeX I get the error message that TeX's main memory is exceeded. I can compile the plots under LuaLaTeX but it doesn't work with LaTeX calling LuaLaTeX. What can I do except deleting some values?

TeX capacity exceeded, sorry [main memory size=3000000].


\tikzset{external/system call={lualatex
        \tikzexternalcheckshellescape -halt-on-error -interaction=batchmode
        -jobname "\image" "\texsource"}}
\tikzexternalize[shell escape=-enable-write18]



scale only axis,
legend style={legend cell align=left,align=left,draw=black}
\addplot [color=gray,line width=.45pt,mark size=.45pt,only marks,mark=*,mark options={solid}]
table [ x expr=\thisrow{tmess}*1e6, y=uoutmess, col sep=comma] {tmessuoutmess.csv};

\addplot [color=black,solid,line width=1.5pt]
table [x expr=\thisrow{tapprox}*1e6, y=uoutapprox, col sep=comma] {tapproxuoutapprox.csv};

\addplot [color=black,loosely dotted,line width=1.5pt]
table [x expr=\thisrow{tsim}*1e6,y=uoutsim, col sep=comma] {tsimuoutsim.csv};

    You have to call pdflatex with the -shell-escape. I'm no expert in MiKTeX, but -src shell-escape looks suspicious and it should probably be -shell-escape. – egreg Mar 6 '15 at 20:40

    Which TeX distribution do you run? Which version of LuaTeX do you have? The latter piece of information is provided on line 1 of the log file. (I run MacTeX2014 on a MacBookPro with 8GByte of RAM, and when I compile your program under LuaTeX 0.79.1, I don't experience the problems you report.) – Mico Mar 6 '15 at 20:41
  • I'm using MiKTex 2.9.4248 and LuaTeX, Version beta-0.76.0-2013062821 (rev 4627) with pdfTeX, Version 3.14159265-2.6-1.40.15 (MiKTeX 2.9 64-bit) under Windows 8.1. - – jlk Mar 6 '15 at 21:16

    No I meant that in your image above you have configured only latex to use shell-escape, so naturally it won't work if you are using pdflatex. I tried your example with pdflatex in a current in miktex (32bit) and it worked without problems. – Ulrike Fischer Mar 6 '15 at 22:50
