如何使用形状怪异的数组来绘制数据？

import numpy as np
import matplotlib.pyplot as plt

# 创建一个形状怪异的数组
irregular_array = [
    [1, 2, 3],
    [4, 5],
    [6, 7, 8, 9]
]

# 将其转换为NumPy数组，方便处理
np_irregular_array = np.array(irregular_array)

# 绘制数据
plt.figure(figsize=(10, 5))
for i in range(np_irregular_array.shape[0]):
    plt.plot(np_irregular_array[i], label=f'Series {i+1}')

plt.title('Plotting Irregular Array Data')
plt.xlabel('Index')
plt.ylabel('Value')
plt.legend()
plt.show()

# 计算最大长度
max_length = max(len(subarray) for subarray in irregular_array)

# 填充数组使其长度一致
padded_array = [subarray + [0] * (max_length - len(subarray)) for subarray in irregular_array]

# 绘制填充后的数组
plt.figure(figsize=(10, 5))
for i in range(len(padded_array)):
    plt.plot(padded_array[i], label=f'Series {i+1}')

plt.title('Plotting Padded Irregular Array Data')
plt.xlabel('Index')
plt.ylabel('Value')
plt.legend()
plt.show()
