I have following pandas dataframe for which I am trying to plot bar graph using Plotly with a dropdown menu to select the by the stock name column, refering this answer.

But I am unsure how do I add multiple columns to the updatemenus as the names of the columns could vary.

import plotly.graph_objects as go
# plotly setup
fig = go.Figure()

# Add traces, starting from First Column. Each column is a stock data.
for mycolumn in df.columns[1:]:
    fig.add_traces( go.Scatter(x=list(df.Quarters), y=list(df[mycolumn])) )

updatemenus = None

for mycolumn in df.columns[1:]:
    # construct menus
    updatemenus = [{'buttons': 
                    [{'method': 'update',
                      'label' : column, # what?
                      'args'  : [{'y': [values_1, values_1b]},] # what?
                     }
                    'direction': 'down',
                    'showactive': True,}
                  ]

# update layout with buttons, and show the figure
fig.update_layout(updatemenus=updatemenus)
fig.show()

The dataframe for ref:
