How to Set Y-Axis Limits in Matplotlib?

 You can set the y-axis limit in Matplotlib by using the ylim function. The ylim function takes two arguments, the lower and upper limits for the y-axis.

Here's an example:

python
import matplotlib.pyplot as plt

# Create some data to plot
x = [1, 2, 3, 4]
y = [1, 2, 3, 4]

# Plot the data
plt.plot(x, y)

# Set the y-axis limit
plt.ylim(0, 5)

# Show the plot
plt.show()

In this example, we first plot some data. Then, we set the y-axis limit to be between 0 and 5 using the ylim function. Finally, we show the plot using the show function.

Note that if you don't set the y-axis limit explicitly, Matplotlib will automatically determine the limits based on the data.
