И я хочу построить его в gnuplot:

 set datafile separator ','
splot 'b0-1_g1-0_100000.dat'u 1:2:3
                                   ^
       All points z value undefined
  

Может кто-нибудь сказать мне, что я делаю не так?
Я использую gnuplot версии 5.2 patchlevel 8

Неважно. Похоже, возникла проблема с кодированием. Но теперь он работает нормально.
