来自x（日期）的Gnuplot y轴值 [英] Gnuplot y-axis value from x(dates)

问题描述

我想知道你可以从x（x店的日期）中获取价值
i有以下日期

  13/3/2014 218.11.11 
 12/4/2014 218.37.12 
 5/5/2014 218.31.34 
 7/5/2015 218.31.10 
 23/5/2014 218.32.21 
 4/6/2014 218.41.14 
  

我们有这些日期，这些ips我想要储存ips在月
示例：
5/2014 - 3 IPS

在gnuplot图表我想打印每个ips每个月有多少
这里是我现在有的

 设置xlabel 'date'
 set title'Gnuplot test graph'
 set ylabel'IPS'
 set terminal png size 1400,500 
 set datafile sep'''
 
 set xdata time 
 set timefmt'％Y-％m-％d％H：％M：％S'
 set xrange [2009/3/27 00:00：2014 / 4/11 22:28] 
 
 set xtics nomirror rotate by -45 
 set grid 
 set term png 
 set output'file.png'
 
 plot'data.dat'使用1：2与点
  

解决方案

为了计数数量相等的x值，可以使用 plot ...平滑频率使用固定数量的 1 y值：

  set xdata time 
 set timefmt'％d /％m /％Y'
 plot'data.dat'使用1：（1）平滑频率
  

这是绘制条目数每天

要按月份对值进行分组，您必须将本月的所有值标准化为本月初的一个月。为此，您可以使用 tm_mday 函数，该函数将根据时间戳记获取当前月份的日期：

  set yrange [0：*] 
 set xdata time 
 set timefmt'％d /％m /％Y'
 set xrange ['01 / 03/2014'：'01/06/2014'] 
 set xtics 30 * 24 * 60 * 60 
设置格式x'％b％Y'
 plot'data.dat'使用（timecolumn（1） - （tm_mday（timecolumn（1）） -  1）* 24 * 60 * 60）:( 1）平滑频率w lp pt 7 ps 2 notitle 
  / pre> 
 
 
  
 
I would like to know how the y can take value from the x (the x store the dates)
i have the following dates
13/3/2014   218.11.11
12/4/2014   218.37.12
5/5/2014    218.31.34
7/5/2015    218.31.10
23/5/2014   218.32.21
4/6/2014    218.41.14
we have these dates and these ips i want store the ips in months 
example:
5/2014 - 3 IPS 

in gnuplot the graph i want to print every how much ips has every month 
here is what i have until now
set xlabel 'Date'
set title 'Gnuplot test graph'
set ylabel 'IPS'
set terminal png size 1400,500
set datafile sep ','

set xdata time
set timefmt '%Y-%m-%d %H:%M:%S'
set xrange ["2009/3/27 00:00":"2014/4/11 22:28"]

set xtics nomirror rotate by -45
set grid
set term png
set output 'file.png'

plot 'data.dat'using 1:2 with points 

解决方案
In order to count the number of equal x-values, you can use plot ... smooth frequency using a fixed number of 1 for the y-values:
set xdata time
set timefmt '%d/%m/%Y'
plot 'data.dat' using 1:(1) smooth frequency
This plots the number of entries for each day. 

To group the values by month, you must normalize all values for a month to the first of this month. For this you can use the tm_mday function, which gets you the day of the current month, based on a timestamp:
set yrange [0:*]
set xdata time
set timefmt '%d/%m/%Y'
set xrange['01/03/2014':'01/06/2014']
set xtics 30*24*60*60
set format x '%b %Y'
plot 'data.dat' using (timecolumn(1) - (tm_mday(timecolumn(1))-1)*24*60*60):(1) smooth frequency w lp pt 7 ps 2 notitle
