如何转置数据帧以及如何散点绘制转置后的df

import pandas as pd

# 创建一个数据帧
df = pd.DataFrame({'A': [1, 2, 3], 'B': [4, 5, 6], 'C': [7, 8, 9]})

# 转置数据帧
transposed_df = df.transpose()

# 打印转置后的数据帧
print(transposed_df)

   0  1  2
A  1  2  3
B  4  5  6
C  7  8  9

import pandas as pd
import matplotlib.pyplot as plt

# 创建一个数据帧
df = pd.DataFrame({'X': [1, 2, 3], 'Y': [4, 5, 6]})

# 转置数据帧
transposed_df = df.transpose()

# 绘制散点图
plt.scatter(transposed_df.index, transposed_df[0])

# 设置图表标题和坐标轴标签
plt.title('Scatter Plot of Transposed DataFrame')
plt.xlabel('Index')
plt.ylabel('Value')

# 显示图表
plt.show()
