Here.
I found out that if I use
from pylab import *
as in the example, it works. But in my app, I'm using
import wx
import matplotlib
from matplotlib.figure import Figure
from matplotlib.backends.backend_wxagg import FigureCanvasWxAgg as FigureCanvas
from matplotlib.backends.backend_wxagg import NavigationToolbar2WxAgg
from matplotlib.font_manager import fontManager, FontProperties
from matplotlib.collections import LineCollection
could that be the culprit?

script:
from pylab import *
import numpy as np
from matplotlib.collections import LineCollection
# We need to set the plot limits, the will not autoscale
ax = axes()
ax.set_xlim((-1,1))
ax.set_ylim((-1,1))
strike = [0,45,90,135]
dip = [10,20,30,40]
listXY = []
for i in range(len(strike)):
beta = np.radians(strike[i])
phi = np.radians(np.arange(-90,92,2))
lamb = np.radians((90 - dip[i]))
alpha = np.arccos(np.cos(phi) * np.cos(lamb))
tq = np.sqrt(2) * np.sin(alpha/2)
sint = np.sin(phi) / np.sin(alpha)
temps = 1 - (sint * sint)
x = tq * np.sqrt(temps)
y = tq * sint
x1 = np.cos(beta) * x + np.sin(beta) * y
y1 = -np.sin(beta) * x + np.cos(beta) * y
listXY.append(zip(x1,y1))
col = LineCollection(listXY, linewidths=1, colors='red', linestyles = 'dotted')
ax.add_collection(col, autolim=True)
show()
