My question is quite simple. I generate a lot of plots for my thesis in PGFplots, which I generate in separate PDF files using the standalone package (could not get shell escape to work properly). The data files are quite large, so I need to compile with LualaTeX (this is also the reason for generating separate PDF files). So my question is: Will using \addplot gnuplot... solve the problem with tex main memory size? Or will I still need to generate separate PDF files?
