How can I remove annotations from a Matplotlib plot?

You can remove annotations in Matplotlib by using the remove() method on the annotation object. Do you have a specific example in mind?

Yes, I added an annotation using ax.annotate(), but I want to remove it.

You can store the annotation in a variable when you create it, like this: annotation = ax.annotate(...). Then, to remove it, just call annotation.remove().

What if I have multiple annotations?

If you have multiple annotations, you can store them in a list and iterate through the list to remove each one using the remove() method.

Can you show me a code example?

Sure! Here's a simple example:

import matplotlib.pyplot as plt

fig, ax = plt.subplots()
ax.plot([1, 2, 3], [1, 4, 9])
annotations = []

for i in range(3):
    annotation = ax.annotate(f'Point {i}', xy=(i+1, (i+1)**2))
    annotations.append(annotation)

# To remove all annotations:
for annotation in annotations:
    annotation.remove()
plt.show()
