Style Plots using Matplotlib

By using style function in Matplotlib we can apply predefined themes or create custom styles which helps in making our plots interactive. We can reuse these templates to maintain consistency across multiple plots. In this article we will see how to use Matplotlib’s built-in styles and efficiently apply them to your plots.

Syntax: plt.style.use('style_name")

• style_name is the name of the style which we want to use.

If we want to explore all the available styles we can print it like this:

from matplotlib import style 
import matplotlib.pyplot as plt 
print(plt.style.available)

Output:

['Solarize_Light2', '_classic_test_patch', 'bmh', ----------------seaborn-whitegrid','tableau-colorblind10']

Example 1: Applying Solarize_Light2 Style

• data = np.random.randn(50): Create an array of 50 random values using numpy's randn() function which generates random values from a standard normal distribution.
• plt.style.use('Solarize_Light2'): Apply Solarize_Light2 style to the plot which helps in making the plot visually consistent with the chosen theme.

import numpy as np 
import matplotlib.pyplot as plt 
from matplotlib import style 
data = np.random.randn(50) 
plt.style.use('Solarize_Light2') 
plt.plot(data) 
plt.show() 

Output:

Example 2: Applying dark_background Style

• plt.style.use('dark_background'): Uses dark_background style which changes plot's background color to dark and adjusts other visual elements accordingly.

import numpy as np 
import matplotlib.pyplot as plt 
from matplotlib import style 
data = np.random.randn(50) 
plt.style.use('dark_background') 
plt.plot(data) 
plt.show() 

Output:

Example 3: Applying ggplot Style

• plt.style.use('ggplot'): Apply ggplot style which helps in giving it a clean and polished look similar to the popular ggplot2 library.
• plt.plot(data, linestyle=":", linewidth=2): Plot data with a dotted line style as specified by linestyle=":" and a line width of 2.

import numpy as np 
import matplotlib.pyplot as plt 
from matplotlib import style 
data = np.random.randn(50) 
plt.style.use('ggplot') 
plt.plot(data, linestyle=":", linewidth=2) 
plt.show() 

Output:

Example 4: Temporarily apply dark_background Style

Note: If we only want to use a style for a particular plot but don't want to change the global styling for all the plots, for that it provides a context manager for limiting the area of styling for a particular plot.

• with plt.style.context('dark_background'): Use a context manager to temporarily apply the dark_backgroundstyle to the plot within the block which ensures that only this plot is affected not others.

 import numpy as np 
import matplotlib.pyplot as plt 
from matplotlib import style 
with plt.style.context('dark_background'): 
	plt.plot(np.sin(np.linspace(0, 2 * np.pi)), 'r-o') 
plt.show() 

Output:

By using Matplotlib's styling features we can easily create visually appealing and consistent plots which helps in enhancing overall presentation of our data.
