Multiple Density Plots with Pandas in Python Last Updated : 03 Jan, 2021 Summarize Comments Improve Suggest changes Share Like Article Like Report Multiple density plots are a great way of comparing the distribution of multiple groups in your data. We can make multiple density plots using pandas plot.density() function. However, we need to convert data in a wide format if we are using the density function. Wide data represents different groups in different columns. We convert data in a wide format using Pandas pivot() function. Let's create the simple data-frame and then reshape it into a wide-format: Example 1: Here we are using this data set. Step 1: Creating dataframe from data set. Python3 import pandas as pd # creating a dataframe df = pd.read_csv(r"gapminder1.csv") df.head() Output: dataset Step 2: Let's group data according to countries in different columns so that we can apply the density() function to plot multiple density plots. Python3 # converting data into wide-format data_wide = df.pivot(columns='continent', values='lifeExp') data_wide.head() Output: Step 3: Now let's plot multiple density plot using plot.density() Python3 import matplotlib.pyplot as plt # calling density() to make # multiple density plot data_wide.plot.density(figsize = (7, 7), linewidth = 4) plt.xlabel("life_Exp") Output : Multiple density plots Example 2: We can also call plot.kde() function on dataframe to make multiple density plots with Pandas. Here we are using the tips dataset for this example, You can find it here. Step 1: Creating dataframe from data set. Python3 import pandas as pd # creating a dataframe df = pd.read_csv(r"tips.csv") df.head() Output: tips_df Step 2: Now apply pivot() function to have dataframe in the wide-format then apply kde() to have multiple density plot. Python3 # Converting to wide dataframe data_wide = df.pivot(columns = 'day', values = 'total_bill') # plotting multiple density plot data_wide.plot.kde(figsize = (8, 6), linewidth = 4) Output: tips multiple D.P Comment More infoAdvertise with us Next Article Multiple Density Plots with Pandas in Python T tejalkadam18m Follow Improve Article Tags : Python Python-pandas Python pandas-plotting Practice Tags : python Similar Reads Python Tutorial - Learn Python Programming Language Python is one of the most popular programming languages.
