Exercise

Adding data to an Axes object

Adding data to a figure is done by calling methods of the Axes object. In this exercise, we will use the plot method to add data about rainfall in two American cities: Seattle, WA and Austin, TX.

The data are stored in two pandas DataFrame objects that are already loaded into memory: seattle_weather stores information about the weather in Seattle, and austin_weather stores information about the weather in Austin. Each of the DataFrames has a "MONTH" column that stores the three-letter name of the months. Each also has a column named "MLY-PRCP-NORMAL" that stores the average rainfall in each month during a ten-year period.

In this exercise, you will create a visualization that will allow you to compare the rainfall in these two cities.

Instructions

100 XP
  • Import the matplotlib.pyplot submodule as plt.
  • Create a Figure and an Axes object by calling plt.subplots.
  • Add data from the seattle_weather DataFrame by calling the Axes plot method.
  • Add data from the austin_weather DataFrame in a similar manner and call plt.show to show the results.
