ERROR Change Data in Plotly Ridgeplot with Button

šŸ“Š Plotly Python
1

I create a Ridgeplot in plotly with go.Violin.
This works but now i want to change the data of each trace with a button.

update_data1= [df1[column] for column in df1]
buttons=list([
                    dict(
                        args={'x':update_data1},
                        label="Datum",
                        method="update"

I think that when I transfer a list in args each element of the list is for one trace. Am I right? But I recive an error Message like:

 Invalid value of type 'builtins.dict' received for the 'args' property of layout.updatemenu.button
        Received value: {'x': [0    -1.640952

    The 'args' property is an info array that may be specified as:

    * a list or tuple of up to 3 elements where:
(0) The 'args[0]' property accepts values of any type
(1) The 'args[1]' property accepts values of any type
(2) The 'args[2]' property accepts values of any type

Does anybody know what Iā€™m doing wrong?

Code Example:

# Data handling
import numpy as np
import pandas as pd
from pathlib import Path
#Plotly
import plotly.graph_objects as go
from plotly.offline import plot

html_path=Path('Test.html')
 
   
df1=pd.DataFrame([np.random.normal(loc=0.0, scale=1.0, size=(100)),
                  np.random.normal(loc=0.0, scale=1.5, size=(100))
                  ]).T

df2=pd.DataFrame([np.random.normal(loc=0.0, scale=1.0, size=(100)),
                  np.random.normal(loc=0.0, scale=1.5, size=(100))
                  ]).T


    
    
fig_ridge = go.Figure()
for column in df1:
    fig_ridge.add_trace(go.Violin(x=df1[column]))
    
fig_ridge.update_traces(orientation='h', 
                      side='positive', 
                      width=3, 
                      points=False,
                      meanline_visible=True)
    
update_data1= [df1[column] for column in df1]
update_data2= [df2[column] for column in df2]
2

here is the rest of the example:

fig_ridge.update_layout(
        updatemenus=[
            dict(
                type = "buttons",
                direction = "left",
                buttons=list([
                    dict(
                        args={'x':update_data1},
                        label="Data1",
                        method="update"
                    ),
                    dict(
                        args={'x':update_data2},
                        label="Data2",
                        method="update"
                    )
                ]),
                pad={"r": 10, "t": 10},
                showactive=True,
                x=0.11,
                xanchor="left",
                y=1.1,
                yanchor="top"
            ),
        ]
    )
