Answer 1

당신 때문에 대수가 정의되지 않은 음의 y 값을가집니다. 그리고 정의되지 않은 점은 줄거리를 방해합니다. using 1:($2 < 0 ? 1/0 : $2)으로 필터링하면 1/0도 마찬가지입니다.

당신은 당신의 yrange 외부 멀리 아주 작은 y 값과 음의 값을 대체 할 수

set logscale y 
set yrange [50:1000] 
set mytics 
set autoscale xfixmax 

plot "Analytic_EField_linear_PW1000.dat" u 1:($2 <= 0 ? 1e-5 : $2) w l lw 3.0 title "Analytic"
