For example, to create a multiline plot, we can draw a line plot for each data series before concluding the figure. Let's try plotting the temperatures of three different cities with the following code:

import matplotlib.pyplot as plt

# Prepare the data series
d = [11,12,13,14,15,16,17]
t0 = [15.3,15.4,12.6,12.7,13.2,12.3,11.4]
t1 = [26.1,26.2,24.3,25.1,26.7,27.8,26.9]
t2 = [22.3,20.6,19.8,21.6,21.3,19.4,21.4]

# Plot the lines for each data series
plt.plot(d,t0)
plt.plot(d,t1)
plt.plot(d,t2)

plt.show()

Here is the plot generated by the preceding code:

This example is adapted from the maximum temperatures of three cities in a week in December 2017. From the graph, can you recognize which two lines are more likely to be representative of cities from the same continent?
