How to independently set horizontal and vertical, major and minor gridlines of a plot?

To set horizontal and vertical, major and minor grid lines of a plot, we can use grid() method.

Steps

Set the figure size and adjust the padding between and around the subplots.
Create a figure and a set of subplots.
Make horizontal grid lines for major ticks.
Locate minor locator on the axes.
Use grid() method to make minor grid lines.
To display the figure, use show() method.

Example

import matplotlib.pyplot as plt
from matplotlib.ticker import MultipleLocator

plt.rcParams["figure.figsize"] = [7.50, 3.50]
plt.rcParams["figure.autolayout"] = True

fig, ax = plt.subplots()

ax.yaxis.grid(which="major", color='r', linestyle='-', linewidth=2)
ml = MultipleLocator(0.10)

ax.xaxis.set_minor_locator(ml)
ax.xaxis.grid(which="minor", color='k', linestyle='-.', linewidth=0.7)

plt.show()
