How can you clear a Matplotlib textbox that was previously drawn?

MatplotlibPythonData Visualization

To clear a Matplotlib textbox that was previously drawn, we can take the following steps −

  • Set the figure size and adjust the padding between and around the subplots.
  • Create x and y data points using numpy.
  • Plot x and y using plot() method.
  • Place characters token on the plot.
  • To clear the text, use text.remove(), where text is a returned artist.
  • To display the figure, use show() method.

Example

import numpy as np
from matplotlib import pyplot as plt

plt.rcParams["figure.figsize"] = [7.50, 3.50]
plt.rcParams["figure.autolayout"] = True

fig, ax = plt.subplots()
x = np.linspace(-10, 10, 100)
y = np.sin(x)
ax.plot(x, y)

text = fig.text(0.5, 0.96, "$y=sin(x)$")

#text.remove()

plt.show()

Output

Now, uncomment the line "text.remove()" and execute the code again. It will produe the following output.
