用gnuplot绘制多个图的Shell脚本

Question

我试图分析多个tcp拥塞控制算法，并试图绘制多个图，但我无法生成一个比较图。

这是我的脚本代码：

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

但是这个脚本把图分成两个子部分(都不是原始人)。

谢谢

按照米格尔的建议，下面是您应该尝试的内容(记住让EOF启动行，在它变得不相关之前的任何空格)：

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
