使用dropdown和matplotlib绘制交互式绘图

import matplotlib.pyplot as plt
from matplotlib.widgets import Dropdown

options = ['折线图', '柱状图', '散点图']

def plot_graph(selected_option):
    if selected_option == '折线图':
        # 绘制折线图的代码
        pass
    elif selected_option == '柱状图':
        # 绘制柱状图的代码
        pass
    elif selected_option == '散点图':
        # 绘制散点图的代码
        pass

fig, ax = plt.subplots()
ax.set_title('交互式绘图')
ax.set_xlabel('X轴')
ax.set_ylabel('Y轴')

dropdown_ax = plt.axes([0.1, 0.95, 0.3, 0.05])
dropdown = Dropdown(dropdown_ax, '图形类型', options)
dropdown.on_changed(plot_graph)

def plot_graph(selected_option):
    if selected_option == '折线图':
        x = [1, 2, 3, 4, 5]
        y = [1, 4, 9, 16, 25]
        ax.plot(x, y)
        plt.draw()

plt.show()
