[Matplotlib-users] real time plotting

[Neal B. <ndb...@gm...>]

I want to update a plot in real time.  I did some goog search, and saw various 
answers.  Trouble is, they aren't working.

Here's a typical example:

import matplotlib.pyplot as plt
import numpy as np
fig=plt.figure()
plt.axis([0,1000,0,1])

i=0
x=list()
y=list()

while i <1000:
    temp_y=np.random.random()
    x.append(i)
    y.append(temp_y)
    plt.scatter(i,temp_y)
    i+=1
    plt.draw()

If I run this, it draws nothing.

This is my matplotlibrc:
backend : Qt4Agg
mathtext.fontset: stix
