如何在MatPlotLib底图中添加标题？

Question

I tried

matplotlib.pyplot.title("Analysis of Tsunamis in Southeast Asia")

but the Python interpreter notes that NameError: name 'matplotlib' is not defined even though I am sure that I imported pyplot earlier:

import matplotlib.pyplot

How can I add a title to my map?

Answer 1

My guess is that you imported pyplot like this

import matplotlib.pyplot as plt
# or from matplotlib import pyplot

In which case you'd need to do

plt.title("Analysis of Tsunamis in Southeast Asia")
# or pyplot.title("Analysis of Tsunamis in Southeast Asia")

Answer 2

I believe that you might have over thought yourself. By importing the routine matplotlib.pyplot, you have brought the subroutines of pyplot into your current work space. Therefore, using the entire name of the function is like saying

matplotlib.pyplot.matplotlib.pyplot.title 

-- which is why it's not defined. Have you tried just calling:

title("Analysis of Tsunamis in Southeast Asia")

After looking at some of my subroutines, I think that might be the solution.

Answer 3

try using

from matplotlib.pyplot import * title("Analysis of Tsunamis in Southeast Asia")
