蟒蛇GNUPLOT从文件

Question

阅读我有以下数据的第一个字段是UNIXTimestamp文件，

1351734672.095 25 
1351734674.449 52 
1351734676.638 612 
1351734680.669 44 
1351734681.121 16 
1351734684.182 15 
1351734684.386 17 
1351734686.823 16 
1351734689.807 22 
1351734689.807 28 

我如何从这个文件加载X，Y到Python？

#!/usr/bin/env python 

from numpy import * 
import Gnuplot 

g = Gnuplot.Gnuplot() 
g.title('My Systems Plot') 
g.xlabel('Date') 
g.ylabel('Value') 
g('set term png') 
g('set out "output.png"') 
proc = open("response","r") 
databuff = Gnuplot.Data(proc.read(), title="test") 
g.plot(databuff) 

目前这不工作...任何想法??

UPDATE：

#!/usr/bin/env python 
from numpy import * 
import Gnuplot 

g = Gnuplot.Gnuplot() 
g.title('My Systems Plot') 
g.xlabel('Date') 
g.ylabel('Response') 
g('set auto x') 
g('set term png') 
g('set out "output.png"') 
g('set timefmt "%s"') 
g('set xdata time') 
g('set xtic rotate by 45 scale 1 font ",2"') 
g('set key noenhanced') 
g('set format x "%H:%M:%S"') 
g('set grid') 


databuff = Gnuplot.File("repo", using='1:2',title="test") 
g.plot(databuff) 

的时间上x轴的值与graph..any想法重叠??

Answer 1

使用Gnuplot.File而不是Gnuplot.Data，就可以得到下面的情节：

#!/usr/bin/env python 

#from numpy import * 
import Gnuplot 

g = Gnuplot.Gnuplot() 
g.title('My Systems Plot') 
g.xlabel('Date') 
g.ylabel('Value') 
g('set term png') 
g('set out "output.png"') 
#proc = open("response","r") 
#databuff = Gnuplot.Data(proc.read(), title="test") 

databuff = Gnuplot.File("response", using='1:2',with_='line', title="test") 
g.plot(databuff) 

---

UPDATE：

有关重叠，你可以改变45到-45：

#g('set xtic rotate by 45 scale 1 font ",2"') 
g('set xtic rotate by -45 scale 1 font ",2"')
