Simple plot in python of a numpy array?

Question

I have an array that looks like this

cplr = array([ 0.01828922, 0.01972157, 0.02342053, ..., 0.25928021, 0.26352547, 0.26883406])

If I say

import matplotlib.pyplot as plt plt(cplr)

TypeError: 'module' object is not callable

How do I plot the contents of a numpy array?

matplotlib.pyplot is a module; the function to plot is matplotlib.pyplot.plot. Thus, you should do

plt.plot(cplr) plt.show()

A good place to learn more about this would be to read a matplotlib tutorial.

Now I get In [66]: plt.plot(cplr) Out[66]: [<matplotlib.lines.Line2D at 0x1077fdad0>] and no plot appears?

You might need plt.show(block=True) depending on your matplotlib backend.
