Exercise on Pandas DataFrame Plots

Solution 1

import pandas as pd 
my_data = pd.read_excel('D:\student.xlsx',index_col='id')
df=my_data['class1'].value_counts()
#print(my_out)
df.plot.line(title="Class and number of Marks");

Solution 2

import pandas as pd 
my_data = pd.read_excel('D:\student.xlsx',index_col='id')
df=my_data[['class1','mark']].groupby(['class1']).agg(['mean'])
df.plot.bar(title="Class1 and Mean mark");

Solution 3

import pandas as pd 
my_data = pd.read_excel('D:\student.xlsx',index_col='id')
df=my_data[['class1','mark']].groupby(['class1']).agg(['mean','max'])
df.plot.bar(title="Class with Mean and Max mark");

Solution 4

import pandas as pd 
my_data = pd.read_excel('D:\student.xlsx',index_col='id')
df=my_data['class1'].value_counts()
#print(my_out)
df.plot.pie(title="Class with number of students");

Solution 5

import pandas as pd 
my_data = pd.read_excel('D:\student.xlsx',index_col='id')
df=my_data['mark']
#print(my_out)
df.plot.density(title="Mark Density");
