Getting vertical gridlines to appear in line plot in matplotlib

Getting vertical gridlines to appear in line plot in matplotlib

To get vertical gridlines to appear in a line plot using Matplotlib, you can use the grid() function and specify the which parameter as 'major' or 'both'. Here's an example:

import matplotlib.pyplot as plt # Sample data x = [1, 2, 3, 4, 5] y = [2, 4, 1, 3, 6] # Create a line plot plt.plot(x, y) # Enable vertical gridlines plt.grid(which='major', axis='x', linestyle='--', color='gray') # Optionally, customize the grid appearance # plt.grid(which='major', axis='x', linestyle='--', color='gray', linewidth=0.5) # Show the plot plt.show()

In this example:

  1. We create a line plot using plt.plot() with sample data x and y.

  2. We enable vertical gridlines using plt.grid(), specifying 'major' for the which parameter and 'x' for the axis parameter to indicate that we want vertical gridlines along the x-axis.

  3. You can customize the appearance of the gridlines by providing additional parameters to plt.grid(), such as linestyle, color, and linewidth.

  4. Finally, we use plt.show() to display the plot with vertical gridlines.

Adjust the which, axis, and other parameters in plt.grid() to customize the gridlines according to your preferences.
