Emile,
from the source code link on that page, I got
# Draw values from the distribution and plot the histogram:
import matplotlib.pyplot as plt
h = plt.hist(np.random.triangular(-3, 0, 8, 100000), bins=200,
normed=True)
plt.show()
Which when I run it I get
Traceback (most recent call last):
File "c:\P26Working\untitled-8.py", line 2, in<module>
h = plt.hist(np.random.triangular(-3, 0, 8, 100000), bins=200, normed=True)
NameError: name 'np' is not defined
Process terminated with an exit code of 1
The import goes OK:
import matplotlib.pyplot as plt
and apparently I have numpy, if that's relevant:
import numpy
but where do I get np?

I think he may be using ipython but putting an "import numpy as np"
should get that code to work.
