Matplotlib上出现未知属性Ticks错误

Question

当我试图将x轴的标签更改为ages_x的标签时，遇到了一个错误。目前，它是x_indexes，这是ages_x的长度。这是我的代码：

import numpy as np
from matplotlib import pyplot as plt

plt.style.use('fivethirtyeight')
ages_x = [25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35]
x_indexes=np.arange(len(ages_x))
width= 0.25
dev_y = [38496, 42000, 46752, 49320, 53200, 56000, 62316, 64928, 67317, 68748, 73752]
plt.bar(x_indexes, dev_y, width=width, color= '#444444', label= 'All Devs')
py_dev_y = [45372, 48876, 53850, 57287, 63016, 65998, 70003, 70000, 71496, 75370, 83640]
plt.bar(x_indexes - width, py_dev_y, width=width,  label= 'Python')
js_dev_y = [37810, 43515, 46823, 49293, 53437, 56373, 62375, 66674, 68745, 68746, 74583]
plt.bar(x_indexes + width, js_dev_y, width=width,  label= 'JavaScript')

plt.title('Median Salary (USD) by Age')
plt.xlabel('Ages')
plt.ylabel('Median Salary (USD)')
plt.legend()
plt.xticks(ticks=x_indexes, labels= ages_x)
plt.tight_layout()

plt.show()

错误如下：

我认为您使用的是Matplotlib 的旧版本

更新到更新的版本，您的代码应该运行良好。我刚刚在matplotlib 3.3.2上运行了您的代码，它运行得很好。
