의이 내가 원하는 가정 해 봅시다 (X를, A) -plot :

<empty> <empty> 8  <empty> <empty> <empty> 16  <empty> ... 
<empty> X  A  B  C  D  A  B  ... 
<inval> <x1> <y8A1> <y8B1> <y8C1> <y8D1> <y16A1> <y16B1> ...

...  ...  ...  ...  ...  ...  ...  ... 

예를 궁극적으로 8 줄, 16 줄, 32 줄 ...).

실제 데이터를 얻으려면 처음 두 줄을 건너 뛰려면 어떻게해야합니까? 나는

plot filename.".csv" u 2:3 every ::3 lc rgb "#00E80000" title "8" 

을 시도하지만 여전히 나에게 파일의 데이터 열에 대한 구분 기호로 공백을 사용하는

"plot_this.p", line 16: warning: Skipping data file with no valid points 

plot filename.".csv" u 2:3 every ::3 lc rgb "#00E80000" title "8" 
                   ^
"plot_this.p", line 16: x range is invalid 

Answer 1

의 gnuplot 기본값을 제공합니다. 당신이 실행하는 데 필요한의 gnuplot으로 CSV (쉼표로 구분) 데이터 파일을 플롯하기 전에 :

set datafile separator ',' 

그 일을 한 후, 첫 번째 플롯 명령은 잘 작동합니다. Gnuplot은 CSV 열 머리글을 처리하는 데 합리적으로 지능적입니다.
