如何使用ipywidgets和matplotlib获得任何类型的交互式绘图

import ipywidgets as widgets
import matplotlib.pyplot as plt

# 创建一个下拉框小部件，用于选择图表类型
chart_type_dropdown = widgets.Dropdown(
    options=['折线图', '柱状图', '散点图'],
    value='折线图',
    description='图表类型:'
)

# 创建一个滑动条小部件，用于调整数据点数量
data_points_slider = widgets.IntSlider(
    value=100,
    min=50,
    max=200,
    step=10,
    description='数据点数量:'
)

def plot_chart(chart_type, data_points):
    x = range(data_points)
    if chart_type == '折线图':
        y = [i**2 for i in x]
        plt.plot(x, y)
    elif chart_type == '柱状图':
        y = [i**2 for i in x]
        plt.bar(x, y)
    elif chart_type == '散点图':
        y = [i**2 for i in x]
        plt.scatter(x, y)
    plt.xlabel('X轴')
    plt.ylabel('Y轴')
    plt.title('交互式绘图')
    plt.show()

output = widgets.interactive_output(plot_chart, {'chart_type': chart_type_dropdown, 'data_points': data_points_slider})
widgets.HBox([chart_type_dropdown, data_points_slider, output])
