Ans:
import pandas as pd
import matplotlib.pyplot as plt
orderlist = [25,36,75,45,68,70]
month = [‘Sept’, ‘Oct’, ‘Nov’, ‘Dec’, ‘Jan’, ‘Feb’]
plt.barh(month, orderlist)
plt.title(“Online Order – 6 Months”)
plt.ylabel(“Month”)
plt.xlabel(“Orders in Numbers”)
plt.show()

78 72 69 81 63 67 65 75
79 74 71 83 71 79 80 69
(a) Create a simple histogram from the above data.
(b) Create a horizontal histogram from the above data.
(c) Create a step type of histogram from the above data.
(d) Create a cumulative histogram from the above data.
Ans:
import pandas as pd
import matplotlib.pyplot as plt
measurement = [78,72,69,81,63,67,65,75,79,74,71,83,71,79,80,69]
11 #(a) Create a simple histogram from the above data.
plt.hist(measurement)
plt.show()
11 #(b) Create a horizontal histogram from the above data.
plt.hist(measurement, orientation=’horizontal’)
plt.show()
11 #(c) Create a step type of histogram from the above data.
plt.hist(measurement, histtype=’step’)
plt.show()
11 #(d) Create a cumulative histogram from the above data.
plt.hist(measurement, cumulative=True)
plt.show()
Output:-
(a)
(b)
(c)
(d)
