Plot the dataset to display Downtrend – Python Pandas
Downward pattern displayed by Time Series Analysis is what we call Downtrend. Let’s say the following is our dataset i.e. SalesRecords2.csv
At first, import the required libraries −
import pandas as pd import matplotlib.pyplot as plt
Load data from a CSV file into a Pandas DataFrame −
dataFrame = pd.read_csv("C:\Users\amit_\Desktop\SalesRecords2.csv")
Casting column to datetime object −
dataFrame['Sold_On'] = pd.to_datetime(dataFrame['Sold_On'])
Create the plot for downtrend −
dataFrame.plot()
Example
Following is the code −
import pandas as pd import matplotlib.pyplot as plt # Load data from a CSV file into a Pandas DataFrame dataFrame = pd.read_csv("C:\Users\amit_\Desktop\SalesRecords2.csv") print("Reading the CSV file...\n", dataFrame) # casting column to datetime object dataFrame['Sold_On'] = pd.to_datetime(dataFrame['Sold_On']) dataFrame = dataFrame.set_index('Sold_On') # Creating the plot dataFrame.plot() plt.show()
Output
This will produce the following output −
