Возникла проблема с использованием
cnuplot в
LaTeX. После компиляции возникает ошибка:
1)Package pgfplots Error: Sorry, the gnuplot-result file 'Nonlinear_Approximatike '>> gnuplot <file>.gnuplot' manually on the respective gnuplot file.. };
2)running in backwards compatibility mode (unsuitable tick labels; missing features). Consider writing \pgfplotsset{compat=1.14} into your preamble.
3)Overwriting file `./data.csv'.
