如何调整条形图及其xtick标签上的间距？

import matplotlib.pyplot as plt

data = [10, 20, 30, 40, 50]
labels = ['A', 'B', 'C', 'D', 'E']
plt.bar(range(len(data)), data)
plt.xticks(range(len(data)), labels)

plt.xticks(range(len(data)), labels, rotation=45)

plt.subplots_adjust(bottom=0.2)

import matplotlib.pyplot as plt

data = [10, 20, 30, 40, 50]
labels = ['A', 'B', 'C', 'D', 'E']

plt.bar(range(len(data)), data)
plt.xticks(range(len(data)), labels, rotation=45)
plt.subplots_adjust(bottom=0.2)

plt.show()
