Change dataframe using a dropdown menu in Plotly
问题
I want to show a single plotly figure where the showed dataframe must change according to a dropdown menu.
我的目标是显示一个Plotly图，其中显示的数据框根据下拉菜单的选择而变化。
I've tried the following code but the only I see changing is the title not the data showed.
我尝试了以下代码，但我只看到标题变化了，而数据没有变化。
My intention is to show either data1 or data2.
我的意图是显示data1或data2中的数据。

I think this works:
import plotly.express as pximport plotly.io as piodata1 = {'x': [1, 2, 3, 4, 5], 'y': [10, 15, 13, 17, 20]}data2 = {'x': [1, 2, 3, 4, 5], 'y': [5, 8, 9, 12, 10]}data3 = {'x': [1, 2, 3, 4, 5], 'y': [1, 2, 1, 2, 2]}fig = px.line(data1, x='x', y='y', title="Data 1")fig.add_scatter(x=data2['x'], y=data2['y'], mode='lines')fig.add_scatter(x=data3['x'], y=data3['y'], mode='lines')fig.update_traces(visible=False)fig.data[0].visible = Truesteps = []for i in range(len(fig.data)):step = dict(method="update",label="Data #" + str(i),args=[{"visible": [False] * len(fig.data)},{"title": "Slider switched to step: " + str(i)}],)step["args"][0]["visible"][i] = Truesteps.append(step)sliders = [dict(active=0,buttons=steps)]fig.update_layout(updatemenus=sliders)fig.show()
(Note: I've translated the code comments and strings into English, as they were originally in Chinese in your provided text.)
