hi,

why does this fail with luatex? also, try \enableregime[utf-8] i got another error message when that's enabled.

You do not need \enableregime[utf-8] in luatex. Everything is already utf-8.

The following works for me (see attached pdf). For some reason, the text in the first node is black. Notice the \tikzstyle line is different from what you had.

BTW, the fix for the arrows is;

  \usetikzlibrary[arrows]


*I think* the problem was with;

  \usemodule[pgfplots]

if I include it get the following in the resulting PDF;
