Why Aren't My Matplotlib Plots Showing Up Inline in My IPython Notebook?

Inline Matplotlib Visualizations in IPython Notebook

In IPython notebook, inline visualization allows matplotlib plots to be displayed directly within the notebook interface. However, under certain circumstances, these visualizations may not appear.

In macOS with Python 2.7.2 and IPython 1.1.0, you may encounter issues with inline plotting despite using "%matplotlib inline" or "%pylab inline" commands. Instead of inline graphics, you might see references to the figure object.

To resolve this issue, try executing "%matplotlib inline" in the first cell of the notebook before importing matplotlib and defining your visualizations. This ensures that inline mode is enabled for the entire notebook session.

Additionally, you can set the following configuration in your config files to permanently enable inline plotting for all IPython kernels:

c.IPKernelApp.matplotlib=inline

By following these steps, you can ensure that matplotlib plots are displayed inline within your IPython notebooks, providing a more intuitive and interactive data visualization experience.
