Hi,lists!
My host is:
Linux localhost.localdomain 2.6.32-220.23.1.el6.i686 #1 SMP Mon Jun 18
09:58:35 CDT 2012 i686 i686 i386 GNU/Linux
And I'm using the matplotlib version is:
python-matplotlib-0.99.1.2-1.el6.i686
I copy the code form pyplot tutorial on page 13,the link is
http://matplotlib.sf.net/Matplotlib.pdf
Here is the code named pyPlot.py in my directory:
import numpy as np
import matplotlib.pyplot as plt
def f(t):
return np.exp(-t) * np.cos(2*np.pi*t)
t1 = np.arange(0.0, 5.0, 0.1)
t2 = np.arange(0.0, 5.0, 0.02)
plt.figure(1)
plt.subplot(211)
plt.plot(t1, f(t1), 'bo', t2, f(t2), 'k')
plt.subplot(212)
plt.plot(t2, np.cos(2*np.pi*t2),'r--')
You're missing a plt.show() at the end.
Using the python is:
[root@localhost ~]# python
Python 2.6.6 (r266:84292, Jun 18 2012, 09:59:14)
[GCC 4.4.6 20110731 (Red Hat 4.4.6-3)] on linux2
When I run the file:
[root@localhost ~]# python pyPlot.py
Xlib: extension "RANDR" missing on display "localhost:10.0".
/usr/lib/python2.6/site-packages/matplotlib/backends/backend_gtk.py:621:
DeprecationWarning: Use the new widget gtk.Tooltip
self.tooltips = gtk.Tooltips()
It did not show any figure, I googling the whole internet,found it could be a
bug in Fedora 12 ,https://bugzilla.redhat.com/show_bug.cgi?id=596649
But it fixed , I don't konw whether it is a bug in Scientific Linux 6.2
because I could not find any information on the internet.
If you don't like the warning, you could clone the bug to RHEL6.
