#Barplot
import matplotlib.pyplot as plt
import numpy as np
Day_names=["Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday", "Sunday"]
N=7
index = np.arange(N)
bar_width = 0.95
bar_height = [1,1.5,1.2,2,0.5,0.75,1]
bar_color = ['b','r','g','yellow','k', 'magenta', 'orange']
bars = plt.bar(index, bar_height, bar_width,alpha=0.5,color=bar_color)
plt.xlabel('Day')
plt.ylabel('Some Value')
plt.title('Bars')
plt.xticks(index + bar_width/2., Day_names)
plt.show()
