I'm trying to plot a temperature map of certain shape. For fewer elements (less than 3000) I have no problem, but for too much elements (more than 250k) I can not produce the file. I get the error TeX capacity exceeded, sorry [token memory size=75830065]., and the process takes more than 10 minutes. I'm using LuaLaTeX.

Here is my current code

documentclass{standalone}

usepackage{pgfplots}

usepgfplotslibrary{clickable,colormaps}

pgfplotsset{

%colormap/hsv

colormap={hsv3}{

rgb255=(255,0,0)

rgb255=(127,255,0)

rgb255=(0,255,0)

rgb255=(0,127,255)

rgb255=(0,0,255)

rgb255=(127,0,255)

rgb255=(255,0,255)},

colormap name=hsv3,

annot/point format={(%d,%d)}

}

standaloneenv{tikzpicture}

begin{document}

begin{tikzpicture}

    begin{axis}[

    x=.15mm,y=.15mm,

    ymin=-0.5,ymax=250.5,

    xmin=-0.5,xmax=1000.5,

    colorbar,

    ticks=none

    ]

    addplot[matrix plot, point meta=explicit,

    clickable coords={(xy): thisrow{t}}

    ] table[x=x,y=y, meta=t]{temps001.dat};

    end{axis}

end{tikzpicture}

end{document}

The temps001.dat has data of a 250x1000 matrix with about 40% of nan values. Here is part of my log

If you really absolutely need more capacity,

you can ask a wizard to enlarge me.

My computer has 8GB of ram, windows 7, core2quad. I alredy tried editing the lualatex.ini opened by initexmf --edit-config-file=pdflatex. It has:

main_memory=200000000000

pool_size=2000000000

save_size=2000000000

extra_mem_bot=2000000000

extra_mem_top=2000000000

font_mem_size=2000000000

A nice solution could be make only the not nan values clickable. Is it possible?
