如何在matplotlib pyplot条形图中反转条形图大小？

import matplotlib.pyplot as plt
import numpy as np

categories = ['A', 'B', 'C', 'D']
values = [10, 20, 15, 25]

plt.barh(categories, values)

plt.gca().invert_yaxis()

plt.show()

import matplotlib.pyplot as plt
import numpy as np

categories = ['A', 'B', 'C', 'D']
values = [10, 20, 15, 25]

plt.barh(categories, values)
plt.gca().invert_yaxis()
plt.show()
