Python - How to plot a Pandas DataFrame in a Bar Graph

Let’s say the following are the contents of our CSV file −

       Car Reg_Price 0      BMW 2000 1    Lexus 1500 2     Audi 1500 3   Jaguar 2000 4  Mustang 1500

Import the required libraries −

import pandas as pd import matplotlib.pyplot as mp

Our CSV file is on the Desktop. Load data from a CSV file into a Pandas DataFrame −

d = pd.read_csv("C:\Users\amit_\Desktop\SalesData.csv") dataFrame = pd.DataFrame(d.head(), columns=["Car","Reg_Price"])

Plot the DataFrame −

dataFrame.plot(x="Car", y="Reg_Price", kind="bar", figsize=(10, 9)) 

Example

Following is the code −

import pandas as pd import matplotlib.pyplot as mp # read csv d = pd.read_csv("C:\Users\amit_\Desktop\SalesData.csv") print("\nReading the CSV file...\n",d) # dataframe dataFrame = pd.DataFrame(d.head(), columns=["Car","Reg_Price"]) # plotting the dataframe dataFrame.plot(x="Car", y="Reg_Price", kind="bar", figsize=(10, 9)) # displaying bar graph mp.show()

Output

This will display the following output −
