在Matplotlib子图文本中添加值和字符串

import matplotlib.pyplot as plt

# 创建子图
fig, ax = plt.subplots()

# 绘制柱状图
x = [1, 2, 3, 4, 5]
y = [10, 20, 15, 25, 30]
ax.bar(x, y)

# 在每个柱状图上添加值和字符串
for i in range(len(x)):
    ax.text(x[i], y[i], str(y[i]), ha='center', va='bottom')
    ax.text(x[i], y[i] + 2, 'Value: ' + str(y[i]), ha='center', va='bottom')

# 设置图表标题和坐标轴标签
ax.set_title('Bar Chart with Text')
ax.set_xlabel('X-axis')
ax.set_ylabel('Y-axis')

# 显示图表
plt.show()
