使用gnuplot繪製多個圖的shell腳本

Question

我想分析多個tcp擁塞控制算法，並試圖繪製多個圖，但我無法做出一個比較圖。

這是我的腳本代碼：

gnuplot -persist <<"EOF" 
set xlabel "time (seconds)" 
set ylabel "Segments (cwnd, ssthresh)" 
plot "./cubic.out" using 1:7 title "snd_cwnd cubic", \ 
"./cubic.out" using 1:($8>=2147483647 ? 0 : $8) title "snd_ssthresh cubic",/ 
    "./reno.out" using 1:7 title "snd_cwnd reno", \ 
    "./reno.out" using 1:($8>=2147483647 ? 0 : $8) title "snd_ssthresh reno" 
    ,/ 
EOF 

但這個腳本劃分圖分成兩個子部分（均未在原點始發）

感謝

繼米格爾的建議，這裏是你應該嘗試（記得有EOF開始行，任何空間之前，它會使它不相關）：

gnuplot -persist <<"EOF" 
set xlabel "time (seconds)" 
set ylabel "Segments (cwnd, ssthresh)" 
plot "./cubic.out" using 1:7 title "snd_cwnd cubic", \ 
"./cubic.out" using 1:($8>=2147483647 ? 0 : $8) title "snd_ssthresh cubic", \ 
    "./reno.out" using 1:7 title "snd_cwnd reno", \ 
    "./reno.out" using 1:($8>=2147483647 ? 0 : $8) title "snd_ssthresh reno" , \ 
EOF
