Keep data while using dropdown menu

📊 Plotly Python
1

HI there,

I would like to use the dropdown button as a data filter to select some data series. However, once I change the menu, the plot disappears.

How can I keep the previous data if it was already visible?

Here is MRE:

import plotly.graph_objects as go
import numpy as np

fig = go.Figure()


for i in range(1,4):
    fig.add_trace(
                            go.Scatter3d
                            (
                                x=np.linspace(0, 1),
                                y=np.linspace(0, 1),
                                z=i*np.linspace(0, 1),
                                mode='markers',
                                name=f"g1_{i}",
                                visible = "legendonly",
                                legendgroup="" ,
                            )
                        )
    
for i in range(4,7):
    fig.add_trace(
                            go.Scatter3d
                            (
                                x=np.linspace(0, 1),
                                y=np.linspace(0, 1),
                                z=i*np.linspace(0, 1),
                                mode='markers',
                                name=f"g2_{i}",
                                visible = "legendonly",
                                legendgroup="" ,
                            )
                        )
    
for i in range(7,10):
    fig.add_trace(
                            go.Scatter3d
                            (
                                x=np.linspace(0, 1),
                                y=np.linspace(0, 1),
                                z=i*np.linspace(0, 1),

                                name=f"g3_{i}",
                                visible = "legendonly",
                                legendgroup="" ,
                            )
                        )
    
fig.update_layout(  
        updatemenus=[
                        dict(    
                            buttons=list([
                                dict(
                                    args=[{"visible": [True if trace.visible else "legendonly" for trace in fig['data']]}],
                                    label=("All"),
                                    method="restyle",
                                ),
                                dict(
                                    args=[{"visible": ["legendonly" if ("g1" in trace.name) else False for trace in fig['data']]}],
                                    label="g1",
                                    method="restyle",
                                ),
                                dict(
                                    args=[{"visible": ["legendonly" if ("g2" in trace.name) else False for trace in fig['data']]}],
                                    label="g2",
                                    method="restyle",
                                ), 
                                dict(
                                    args=[{"visible": ["legendonly" if ("g3" in trace.name) else False for trace in fig['data']]}],
                                    label="g3",
                                    method="restyle",
                                ),                                 
                            ]),
                            direction = "down",
                            pad={"r": 10, "t": 10},
                            showactive=True,
                            x=0.75,
                            xanchor="center",
                            y=1.1,
                            yanchor="top"
                        )])

Also the “All” button just selects everything and does check work as intended. If the trace is visible keep it visible otherwise put it as “legendonly”.

Would appreciate some insight into this.
