Python Seaborn Categorical scatterplots: Strip Plot

Strip plot can be plotted like a scatter plot where one variable is a categorical value. It is also a good alternative for scatter plots when we need to plot overlapping data points in observation because a scatter plot in the case of 2 similar data points are superimposed and in a strip plot, the values are juxtaposed where the jitter argument is True.

It is a graphical data analysis technique for summarizing a univariate dataset.

It is also a good complement to the box or violin plot because in the strip plot all the observations are shown along with some representation of the underlying distribution.

Syntax

seaborn.stripplot(*, x=None, y=None, hue=None, data=None, order=None, 
hue_order=None, jitter=True, dodge=False, orient=None, color=None, palette=None, 
size=5, edgecolor='gray', linewidth=0, ax=None, **kwargs)

Parameters

  • x, y, hue: It is a parameter that is used for long-from of data input.
  • data: It takes datasets for plotting.
  • order, hue_order: It is the order to plot the categorical levels in.
  • jitter: It is the amount of jitter to apply along the categorical axis only.
  • orient:¬†Orientation of the plot along the vertical or horizontal axis.

Examples

import pandas as pd
import numpy as np
import matplotlib.pyplot as plt
import seaborn as sns

data=sns.load_dataset('geyser')

#Create a simple STRIP PLOT
sns.stripplot(x='kind',y='waiting',data=data)

Output

strip

#using jitter
sns.stripplot(y='waiting',x='kind',data=data, jitter=0.5)

Output

jitter

#draw the line around the point using line width
sns.stripplot(y="waiting", x="kind", data=data,linewidth=1,jitter=0.5)

Output

line width

# simple scatter plot 
sns.scatterplot(x='kind',y='waiting',data=data)

Output

scatter

In the above example, you can see the difference between a scatter and a strip plot. Strip plot has avoided the overlapping of two same data points in the observation and scatter plot has superimposed them.

Strip Plot with Box Plot

#strip plot with boxplot
plt.figure(figsize=(10,5))
sns.boxplot(y='waiting', x='kind', data=data)
sns.stripplot(y='waiting', x='kind', data=data,color='black',alpha=0.5,linewidth=1)

Output

box

Strip Plot with Violin Plot

plt.figure(figsize=(10,5))
sns.violin(y='waiting', x='kind', data=data)
sns.stripplot(y='waiting', x='kind', data=data,color='black',alpha=0.5,linewidth=1)

Output

violin
