Hello! Using I typed the following code in the cell of my worksheet:

import matplotlib.pyplot as plt
plt.plot([1, 3, 2, 4])

Unfortunately there isn't any graph under the cell. What should I do? Thanks.

You just need to modify your last line.

import matplotlib.pyplot as plt
plt.plot([1, 3, 2, 4])

You might want to include x-coordinates to the get plot you want.

import matplotlib.pyplot as plt
plt.plot([1,2,3,4],[1, 3, 2, 4])

Also, you can get a nice plot in Sage with list_plot that might do the job for you.

`points(...)` or `line(...,linestyle='')` are also good ideas.
