How to use seaborn to visualise a Pandas dataframe?

This recipe helps you use seaborn to visualise a Pandas dataframe

Recipe Objective

Have you ever feel a need to visualize the data in various form. Visualizing the data give us a better idea how our dataset is distributed.

So this is the recipe on how we use seaborn to visualise a Pandas dataframe.

Step 1 - Import the library

import pandas as pd import random import matplotlib.pyplot as plt import seaborn as sns

We have imported various modules like pandas, random, matplotlib and seaborn which will be need for the dataset.

Step 2 - Setting up the Data

We have created a empty dataset and then by using random function we have created set of random data and stored in X and Y. We have used print function to print the dataset. df = pd.DataFrame() df['x'] = random.sample(range(1, 50), 25) df['y'] = random.sample(range(1, 100), 25) print(); print(df.head()) print(); print(df.tail())

Step 3 - Ploting different Plots

So we will be ploting different plots by using seaborn.

  • First we are ploting Scatterplot by passing the required parameters
  • sns.lmplot('x', 'y', data=df, fit_reg=False)
  • Now we are ploting a regression line which fits the data
  • sns.lmplot('x', 'y', data=df, fit_reg=True)
  • Now we are ploting a density plot for the data
  • sns.kdeplot(df.y); plt.show() sns.kdeplot(df.y, df.x); plt.show() sns.distplot(df.x); plt.show()
  • Now we are ploting a histogram for the data
  • plt.hist(df.x, alpha=.3) sns.rugplot(df.x) plt.show()
  • Now we are ploting a Boxplot for the data
  • sns.boxplot([df.y, df.x]) plt.show()
  • Now we are ploting a Violin Plot for the data
  • sns.violinplot([df.y, df.x]) plt.show()
  • Now we are ploting a Heatmap for the data
  • sns.heatmap([df.y, df.x], annot=False, fmt="d") plt.show()
  • Finally we are ploting a clustermap for the data
  • sns.clustermap(df) plt.show()
So the output comes as:

    x   y
0  15  22
1  36  61
2  39  71
3   3  46
4  38  85

     x   y
20   6  49
21  19  20
22   9  73
23  33  79
24  40  59
