Matplotlib - Grid Line Style

Matplotlib - Grid Line Style

In Matplotlib, you can choose a line style for the grid. For example, you can set dashed lines, dotted lines, etc., using line style.

To set a specific style for the lines in grid, call the grid() function from matplotlib.pyplot and pass required value such as 'dashed', 'dotted', 'dashdot', '--', etc., as the argument for the linestyle parameter.

By default the grid lines are displayed as solid lines.

For example, plt.grid(linestyle='dashed') displays the grid with dashed lines.

import matplotlib.pyplot as plt
plt.grid(linestyle='dashed')

The following is a list of all Matplotlib Linestyle Values.

linestyle	Description
'-'	Solid Line
'--'	Dashed Line
':'	Dotted Line
'-.'	Dash-dot Line
'' or 'None' or None	No Line
' '	No Line
'-'	Solid Line (Alias for 'solid')
'dotted'	Dotted Line (Alias for ':')
'dashed'	Dashed Line (Alias for '--')
'dashdot'	Dash-dot Line (Alias for '-.')

Examples

1. Line style = "dashed" for Grid in Matplotlib

In the following program, we shall display dashed lines in the grid using linestyle='dashed'.

Python Program

import matplotlib.pyplot as plt

# Example data
x = [1, 2, 3, 4, 5]
y = [10, 20, 25, 55, 40]

# Plot the data
plt.plot(x, y, marker='o')

# Grid with specific linestyle
plt.grid(linestyle='dashed')

# Show the plot
plt.show()

Output

2. Line style = "dashdot" for Grid in Matplotlib

In the following program, we shall display dashdot lines in the grid using linestyle='-.'.

Python Program

import matplotlib.pyplot as plt

# Example data
x = [1, 2, 3, 4, 5]
y = [10, 20, 25, 55, 40]

# Plot the data
plt.plot(x, y, marker='o')

# Grid with specific linestyle
plt.grid(linestyle='-.')

# Show the plot
plt.show()

Output
