Pandas: Plotting Exercise-9 with Solution

Write a Pandas program to draw a horizontal and cumulative histograms plot of opening stock prices of Alphabet Inc. between two specific dates.

Use the alphabet_stock_data.csv file to extract data.

alphabet_stock_data:

alphabet_stock_data Table

Sample Solution:

Python Code :

import pandas as pd
import matplotlib.pyplot as plt
df = pd.read_csv("alphabet_stock_data.csv")
start_date = pd.to_datetime('2020-4-1')
end_date = pd.to_datetime('2020-4-30')                         
df['Date'] = pd.to_datetime(df['Date']) 
new_df = (df['Date']>= start_date) & (df['Date']<= end_date)
df1 = df.loc[new_df]
df2 = df1[['Open']]
plt.figure(figsize=(15,15))
df2.plot.hist(orientation='horizontal', cumulative=True)
plt.suptitle('Opening stock prices of Alphabet Inc.,\n From 01-04-2020 to 30-04-2020', fontsize=12, color='black')
