gnuplot - 如何在顶部显示中线

Question

我有一个方便的脚本正在运行 ab然后生成情节。但是有一个问题，它向我展示了每一点(这很好)，但是我也想看到它们之间的平均“线”。我会在图片中展示更多。

那么有没有办法在顶部添加中/中游侠？

脚本

#!/usr/local/bin/gnuplot

set terminal jpeg size 1280,720
set size 1, 1
set output OUTPUT
set title OUTPUT
set key left top
set grid y
set xdata time
set timefmt "%s"
set format x "%S"
set xlabel 'seconds'
set ylabel "response time (ms)"
set datafile separator '\t'
plot INPUT every ::2 using 2:5 title 'response time' with points
exit

输出



输出(我想要的)

Answer 1

这可以通过 smooth unique 来完成选项:

This makes the data monotonic in x; points with the same x-value are replaced by a single point having the average y-value. The resulting points are then connected by straight line segments.

plot INPUT every ::2 using 2:5 title 'response time' with points,\
     '' every ::2 using 2:5 smooth unique title 'average' with lines
