gnuplot - 设置xtics <start> , <incr> 在gnuplot中不起作用(set xtics by <start>, <incr> in gnuplot does not work)

I plot with gnuplot the following:

(我用gnuplot绘制以下内容:)

$Data <<EOD

time_,value

1-23:59:58,1

1-23:59:59,2

2-00:00:00,3

2-00:00:01,4

2-00:00:02,5

EOD

set term png  size 800,600 

set output "ask.png"

set datafile separator comma

set grid

set xdata time

set timefmt "%d-%H:%M:%S" 

set format x "%H:%M:%S" 

set xtics nomirror

set autoscale xfix

set autoscale x2fix

startnumber=1

xticdata=2

mxticdata=2

set xtics xticdata rotate

set mxtics mxticdata

set x2data

set x2tics startnumber, xticdata rotate

set mx2tics mxticdata

set link x2 via x+1 inverse x-1


plot $Data using 1:2 title columnheader(2)

set output

The output is alright, but you can see from the attached figure that the labels on x2-axis are big numbers, which is not what I want.

(输出没问题,但是从附图中可以看到x2轴上的标签是大数字,这不是我想要的。)

I want to get labels like "1,3,5...".

(我想获取类似“ 1、3、5 ...”的标签。)

So what's wrong with my code?

(那么我的代码有什么问题呢?)

And how to correct it?

(以及如何纠正呢?)

Thanks.

(谢谢。) 在此处输入图片说明

the quickest fix would be

(最快的解决办法是)

set link x2 via x-86397 inverse x+86397

But it depends what timesteps you have and what numbers you have in column 2. If your time step it is strictly regular and 1 second, and column 2 just counts up, then column 2 is redundant.

(但这取决于您在第2列中使用的时间步长和编号。如果您的时间步长严格固定且为1秒,而第2列只是递增计数,则第2列是多余的。)

Timedata is handled internally as seconds from 01.01.1970 00:00:00.

(从1970年1月1日00:00:00起,时间数据在内部以秒为单位进行处理。)

One day has 86400 seconds.

(一天有86400秒。)
