how to color area under a curve matplot lib python in python

To color the area under a curve in Matplotlib, the fill_between function can be used. Here is an example code snippet that demonstrates how to use the fill_between function:

main.py
import matplotlib.pyplot as plt
import numpy as np

# Generate some data for the curve
x = np.linspace(0, 10, 100)
y = np.sin(x)

# Create the plot with the curve
fig, ax = plt.subplots()
ax.plot(x, y)

# Fill the area under the curve with a color
ax.fill_between(x, y, color='blue', alpha=0.5)

# Show the plot
plt.show()

In the fill_between function, the x and y arrays represent the points that define the curve. The color parameter sets the color of the fill, and the alpha parameter sets the transparency of the fill.
