radio = plt.radioButtons(rax, options) AttributeError: module 'matplotlib.pyplot' has no attribute 'radioButtons'

抱歉，我的回答有误，`radioButtons` 不是 `matplotlib.pyplot` 模块的函数，正确的函数名应该是 `RadioButtons`，而且需要从 `matplotlib.widgets` 模块中导入，所以你需要将代码中的 `radioButtons` 改为 `RadioButtons`，并添加 `from matplotlib.widgets import RadioButtons` 语句，即：

import pandas as pd
import matplotlib.pyplot as plt
from matplotlib.widgets import RadioButtons
import random

# 读取CSV文件
df = pd.read_csv("data.csv")

# 分类处理
abc_cols = ["ABC", "DFG", "TBC", "DHHG", "lop", "kki"]
cat_cols = [col for col in df.columns if col.startswith("CAT")]
dog_cols = [col for col in df.columns if col.startswith("DOG")]
fish_cols = [col for col in df.columns if col.startswith("Fish")]
food_cols = [col for col in df.columns if col.startswith("food")]

# 绘制曲线图
fig, axs = plt.subplots(4, 1, figsize=(8, 8), sharex=True)
colors = ['r', 'g', 'b', 'y', 'm', 'c']  # 随机颜色
axs[0].set_title("ABC Titles")
for col, color in zip(abc_cols, colors):
    axs[0].plot(df[col], color=color)
axs[1].set_title("CAT Titles")
for col, color in zip(cat_cols, colors):
    axs[1].plot(df[col], color=color)
axs[2].set_title("DOG Titles")
for col, color in zip(dog_cols, colors):
    axs[2].plot(df[col], color=color)
axs[3].set_title("Fish and Food Titles")
for col, color in zip(fish_cols+food_cols, colors):
    axs[3].plot(df[col], color=color)

# 添加筛选器
options = ["ABC Titles", "CAT Titles", "DOG Titles", "Fish and Food Titles"]
axcolor = 'lightgoldenrodyellow'
rax = plt.axes([0.91, 0.5, 0.08, 0.15], facecolor=axcolor)
radio = RadioButtons(rax, options)

# 点击筛选器时更新图形
def update(label):
    for i, title in enumerate(options):
        if label == title:
            axs[i].set_visible(True)
        else:
            axs[i].set_visible(False)

radio.on_clicked(update)

plt.show()

这样就可以正常运行了。
