How do I display Matplotlib plots inline in my IPython Notebook?

Inline Matplotlib Plots in IPython Notebook

Issue:

When running an IPython notebook with Python and Matplotlib, inline graphics are not being displayed. Instead, the output displays as a figure object.

Question:

How can I resolve this issue to display Matplotlib plots inline within the notebook?

Answer:

To successfully embed Matplotlib plots inline, ensure that the %matplotlib inline directive is executed in the first cell of the notebook. This step initializes the necessary configuration for displaying graphics inline. To prevent repetition, you can also set a default configuration by setting c.IPKernelApp.matplotlib to inline in your IPython configuration files. This will automatically start all IPython kernels in inline mode.

Here's an updated example that should resolve the issue:

%matplotlib inline

import matplotlib
import numpy as np
import matplotlib.pyplot as plt

x = np.linspace(0, 3*np.pi, 500)
plt.plot(x, np.sin(x**2))
plt.title('A simple chirp')

Executing this code within an IPython notebook should now display the plot inline, rather than as a separate window or figure object.
