Here is the dataframe that I’m working with in python.

Here is the code that I’m using. The subplot part I got off a datacamp module.
fig, ax = plt.subplot()
plt.show()
But when I go to plot the mtcars dataset, one variable against the other, I get a blank canvas. Why is that? I don’t see how the code is different than what I am looking at on DataCamp.
ax.plot(mtcars['cyl'], mtcars['mpg'])
plt.show()
The answer from below is helpful and gets me closer to a solution but it is giving me lines instead of a scatterplot?
fig, ax = plt.subplot()
plt.show()
>Solution :
import matplotlib.pyplot as plt
plt.plot(df['cyl'], df['mpg'])
plt.show()
or:
ax = plt.subplot(2, 1, 1)
ax.plot(df['cyl'], df['mpg'])
plt.show()
