Hi Christophe
I can generally not recommend using more columns than you actually read
(use) from, further a loaded file will take much space and will decrease
performance of the compilation.
I can recommend to write a script, using awk or how you like it, to extract
the columns that you wish to plot. This will let you have several files, but
a MUCH faster compilation. Consider that everytime you plot you have to
re-read the file, if you have not pre loaded it.
This is my general recommendation for anybody wishing to plot large data
sets.
I do not know how many is the limit, but try to split it up and see the
difference in compilation time.
