I'm trying to use sagetex to plot 3d graphics in LaTeX. I can get the basic plot to work but there isn't enough detail. When I try to create more points in my plot I get the message: "! Unable to read an entire line---bufsize=200000. Please increase buf_size in texmf.cnf.". I found a texmf.cnf file on my system, made a copy of it with a modification of the bufsize to read "buf_size = 1000000" and uploaded it to my Cocalc project. Following this FAQ page I created ~/texmf/tex/latex/local and moved my texmf.cnf file there, When that didn't work, I tried texhash ~/texmf as suggested. However, I still get the message "! Unable to read an entire line---bufsize=200000. Please increase buf_size in texmf.cnf."
How do I change the bufsize on Cocalc? Are there any guidelines on a reasonable buf_size value to increase to?
