Methods to Hide Legend from Seaborn Pairplot
A pairplot is a useful Seaborn function that creates a grid of scatter plots for each pair of variables in a dataset. It is particularly helpful for exploring relationships between multiple variables. However, the default behavior includes a legend, which may not always be necessary.
There are several methods to hide the legend from a Seaborn pairplot. We will explore the following approaches:
- Using the
legendparameter - Using the
remove()method - Using
plt.legend() - Using
get_legend()
Method 1: Using the legend Parameter
The simplest way to hide the legend is by setting the legend parameter to False in the pairplot function. This method is straightforward and effective.
import seaborn as sns
import matplotlib.pyplot as plt
import pandas as pd
df = pd.DataFrame({
'id': ['1', '2', '1', '2', '2', '6', '7', '7', '6', '6'],
'x': [123, 22, 356, 412, 54, 634, 72, 812, 129, 110],
'y': [120, 12, 35, 41, 45, 63, 17, 91, 112, 151]
})
# Create pairplot without legend
sns.pairplot(df, x_vars='x', y_vars='y', hue='id', height=3, plot_kws={'legend': False})
plt.show()
Output:
Using the legend Parameter
Method 2: Using the remove() Method
If you have already created the pairplot and want to remove the legend, you can access the legend object and call the remove() method.
import seaborn as sns
import matplotlib.pyplot as plt
import pandas as pd
# Sample data
df = pd.DataFrame({
'id': ['1', '2', '1', '2', '2', '6', '7', '7', '6', '6'],
'x': [123, 22, 356, 412, 54, 634, 72, 812, 129, 110],
'y': [120, 12, 35, 41, 45, 63, 17, 91, 112, 151]
})
# Create pairplot
g = sns.pairplot(df, x_vars='x', y_vars='y', hue='id', height=3)
# Remove legend
g._legend.remove()
plt.show()
Output:
Using the remove() Method
Method 3: Using plt.legend()
You can also use plt.legend() to remove the legend by passing empty lists and setting frameon to False.
import seaborn as sns
import matplotlib.pyplot as plt
import pandas as pd
# Sample data
df = pd.DataFrame({
'id': ['1', '2', '1', '2', '2', '6', '7', '7', '6', '6'],
'x': [123, 22, 356, 412, 54, 634, 72, 812, 129, 110],
'y': [120, 12, 35, 41, 45, 63, 17, 91, 112, 151]
})
# Create pairplot
g = sns.pairplot(df, x_vars='x', y_vars='y', hue='id', height=3)
# Remove legend using plt.legend()
plt.legend([], [], frameon=False)
plt.show()
Output:
Using plt.legend()
How to Hide Legend from Seaborn Pairplot
Seaborn is a powerful Python library for data visualization, built on top of Matplotlib. It provides a high-level interface for drawing attractive and informative statistical graphics. One common task when creating visualizations is to manage the legend, which can sometimes clutter the plot or distract from the main data points. This article will guide you through various methods to hide the legend from a Seaborn pairplot, ensuring your visualizations remain clean and focused.
