# Adjust layout to make room for the table:

plt.subplots_adjust(left=0.2, bottom=0.25)

# 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()
