I have exported four Matlab plots with matlab2tikz to tikz. Each plot has 10000 scatter points. When I try to use it in LaTeX I'm getting an out of memory error. I have also converted the figures to eps but the eps files are very big and take long to load when viewing the PDF. Also the font size is very small in the eps files.
How can I solve this issue? Can I perhaps send somebody my four tikz files for e.g. conversion to PDF (or other format)?
Edit: I have uploaded the files here: https://1drv.ms/f/s!AlkQuYgB1McYiDeZiTLqyJKanjlD
