1351734681.121 16         


        

Answer 1

Using Gnuplot.File instead of Gnuplot.Data, it is possible to get the following plot:

#!/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:

For the overlap, you can change 45 to -45 :

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