问题描述

我有两个并行工作的设备,问题是其中一个设置了12小时不同于另一个(即,而不是17:00,标记为05:00)。
我试图应用这个解决方案:
如何在gnuplot中读取12h(AM / PM)时间格式



这样:我的数据是这样的:

 #时间浓度(#/cm³)
05:00:14 5902
05:00:15 5898
05:00:16 5989
05:00:17 5921

我正在运行下面的代码:

pre code $ set $ d $ time $ $ $ $ b set format x'%H:%M'
set xlabeltime

plot< awk'{time = $ 1; if substr(time,1,2) = 12)add = 12; else add = 0}'data1.txtu 1:2 t'CPC1'wl,\
data2.txtu 1:2 t'CPC2'wl

暂停-1

然而,被处理的data1文件没有被绘制, data2具有正确的时间表。任何想法的解决方案?



在此先感谢您!

可以在gnuplot里直接加上12个小时。在内使用语句使用 timecolumn 来获得以秒为单位的时间,然后添加12小时(43200秒) p>

  set xdata time $ b $ set timefmt'%H:%M:%S'
set format x'% H:%M'
设置xlabeltime
设置样式数据行

使用(timecolumn(1)+ 43200)绘制'data1.txt':2'CPC1 ',\
'data2.txt'using 1:2 t'CPC2'


I have two devices working in paralell, the problem is that one of them was set up 12 hours different than the other (that is, instead of 17:00, marked 05:00). I'm trying to apply this solution: How to read 12h (AM/PM) timeformat in gnuplot

In this way: My data are like this:

#Time   Concentration (#/cm³)   
05:00:14    5902    
05:00:15    5898    
05:00:16    5989    
05:00:17    5921    

And I'm running the folowing code:

set xdata time
set timefmt '%H:%M:%S'
set format x '%H:%M'  
set xlabel "time"

plot  "< awk '{time = $1; if substr(time,1,2) <= 12) add = 12; else add = 0}' data1.txt" u 1:2 t 'CPC1' w l, \
      "data2.txt" u 1:2 t 'CPC2' w l

pause -1

However, the treated data1 file is not being plotted, only the data2 which has the correct timescale. Any idea of solution?

Thanks in advance!

解决方案

You can add the 12 hours directly inside gnuplot. Inside the using statement use timecolumn to get the time in seconds and then add your 12 hours (43200 seconds)

set xdata time
set timefmt '%H:%M:%S'
set format x '%H:%M'  
set xlabel "time"
set style data lines

plot 'data1.txt' using (timecolumn(1) + 43200):2 t 'CPC1',\
     'data2.txt' using 1:2 t 'CPC2'
