Fix The Error “‘axessubplot’ object is not subscriptable error”

Python is a widely used and well-recognized programming language that plays an important role in the world of programming and the life of programmers and developers. It helps develop web applications as well as web pages. Programming is incomplete without Python. Some beginners and learners want to excel in this language. Python has libraries and frameworks that make it simpler for programmers to access the code and develop a program. Matplotlib is a Python library that is used for creating animated, static, and interactive visualizations. When you are working with the Matplotlib, you may get the error “‘axessubplot’ object is not subscriptable error”.

You don’t need to worry when you encounter this error as there is no such error warning that can’t be fixed. You only need the determination to get through it. As you are here to get the issue fixed, we won’t let you go empty hand as we have the tips and solutions to help you deal with it. Check out how you get the error message

How the error pops up

When you are trying to design a box with the ‘x’ variable that has been contained in two dataframes, namely df1 and df2, respectively, you end in the error. Have a look at the code that shows a dead end with an error

fig, axs = plt.subplots()
axs[0, 0].boxplot([df1['x'], df2['x']])
plt.show();

This is what you get in return

---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)
<ipython-input-108-ce962754d553> in <module>()
----> 2 axs[0, 0].boxplot([df1['x'], df2['x']])
      3 plt.show();

TypeError: 'AxesSubplot' object is not subscriptable

You must be wondering how to resolve it. Check out the way to fix it

How To Fix the Error “‘axessubplot’ object is not subscriptable error”

We have a very simple solution to help you fix it. The indexing notation causes the error so you need to remove it on the axes object in plt.subplot() to fix it.

If you don’t pass an argument, you get the error as it creates non-subscriptable axes:

 fig, axes = plt.subplots()

If you pass an argument, it can create a subscriptable axes array that is the subplot’s one-dimensional array:

fig, axes = plt.subplots(3)

In the case of two passed arguments, subplots of the two-dimensional array are created because of a subscriptable array of axes:

fig, axes = plt.subplots(3, 2)

These are the reasons you get the error warning. Let’s figure out the solution to handle the exception

Solutions to Fix the Error Warning

To get the issue resolved, you need to check the axes object you get from plt.subplots() and remove the indexing notation. Take a look at the code to follow

import matplotlib.pyplot as plt

fig, axes = plt.subplots()
axes.plot([1, 2, 3], [9, 8, 7])  # not: axes[0, 0]
plt.show()

It helps you solve the error.

Conclusion

And that’s how you get rid of the error “‘axessubplot’ object is not subscriptable error”. It is this simple to fix the exception. I hope you enjoyed it!
