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?
