Matplotlib之Bar Chart

Matplotlib之Bar Chart:

# Adjust layout to make room for the table:

# plt.ylabel("Loss in ${0}'s".format(value_increment))
plt.ylabel('Break counts')
# print(values)
plt.yticks(values, ['%d' % val for val in values])
plt.xticks([])
plt.title('Break Recon Summary')
 
plt.show()
