Adjusting Text background transparency in Matplotlib
To adjust text background transparency in matplotlib, we can change the alpha value in the dictionary of bbox with facecolor='red' and alpha='0.4'.
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 data points using plot() method.
Now use text() method to adjust the text background with fontdict and bbox dictionaries at x=-1.0 and y=4.0.
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 x = np.linspace(-2, 2, 10) y = np.exp(x) plt.plot(x, y) plt.text(-1.0, 4.0, 'y=exp(x)', fontdict=dict(fontsize=15, fontweight='bold'), bbox=dict(facecolor='red', alpha=0.4, edgecolor='black')) plt.show()
