How to Change Plot Size in Matplotlib in Python

You can change the size of a plot in Matplotlib by setting the figure size before creating the plot. The figure size is specified in inches, and you can adjust both the width and height to control the overall size of the plot.

Here’s how to change the plot size in Matplotlib:

import matplotlib.pyplot as plt

# Set the figure size (width, height) in inches
plt.figure(figsize=(8, 6))  # Adjust the values as needed

# Create a simple plot
x = [1, 2, 3, 4, 5]
y = [10, 15, 13, 17, 8]
plt.plot(x, y)

# Add labels and title (optional)
plt.xlabel("X-axis")
plt.ylabel("Y-axis")
plt.title("Sample Plot")

# Show the plot
plt.show()

In this example:

1. We import the matplotlib.pyplot module, commonly used for creating plots in Matplotlib.
2. We use plt.figure(figsize=(8, 6)) to set the figure size. You can adjust the figsize parameter to your preferred width and height values in inches.
3. We create a simple plot using plt.plot().
4. Optionally, we add labels to the axes and a title using plt.xlabel(), plt.ylabel(), and plt.title().
5. Finally, we display the plot using plt.show().

By adjusting the figsize parameter, you can control the size of the plot to fit your requirements. The values specified in figsize correspond to the width and height of the figure in inches.
