How to remove the frame from a Matplotlib figure in Python?

To remove the frame (also known as axes spines) from a Matplotlib figure, you can turn off individual spines which are the borders of the plotting area. There are four spines: 'left', 'right', 'bottom', and 'top'. You can use the spines[<spine_name>].set_visible(False) method to hide them.

Here's a step-by-step guide:

1. Setup:

Ensure you have Matplotlib installed:

pip install matplotlib

2. Remove the frame:

Here's an example of plotting a simple graph and removing its frame:

import matplotlib.pyplot as plt # Sample data x = [1, 2, 3, 4] y = [1, 4, 2, 3] fig, ax = plt.subplots() # Plot the data ax.plot(x, y) # Remove all the spines for spine in ['left', 'right', 'top', 'bottom']: ax.spines[spine].set_visible(False) # Optionally, if you also want to remove ticks and labels ax.yaxis.set_ticks([]) ax.xaxis.set_ticks([]) plt.show()

In this code:

  • We first plot a simple line graph using ax.plot(x, y).
  • We then loop over each spine and set its visibility to False to hide it.
  • Optionally, we can also remove the ticks and labels on both the x and y axes if desired.

This results in a plot where the data is shown without any surrounding frame, ticks, or labels.
