Hey,
unfortunately I got to walk away from using pgfplots like that again. It's just
to slow.
I have a document with nothing but 2 groupplots with 2 graphs and 4 or 5
addplots each.
All are plot from the same CSV file with 3600 lines, which is filtered by 3
onlyif commands to 50 data points per addplot.
On my machine pdflatex on that documents take 95s. (CPU is i5 @ 1.9 GHz, SSD).
So I will split up data in chunks of CSV files before plotting.
Best,
Florian
