Hello,

is there a way we can select different trace using the buttons? below is my attempt trying to do it using a for loop but it’s not working and I have no idea how to, please help.

> py.init_notebook_mode(connected = False)
> data = []
> Layout = []
> countries = data['country'].unique()
> i = 0
> for country in countries:
> trace = go.Bar(
> x = data.loc[data['country'] == country, 'sector'].value_counts().index,
> y = data.loc[data['country'] == country, 'sector'].value_counts().values,
> )
> data.append(trace)
> 
> layout = go.Layout(
> updatemenus = [
> dict(
> type = 'dropdown',
> buttons = [
> dict(
> label = country,
> args = [data[i]],
> method = 'restyle'
> ),
> ]
> )]
> )
> i += 1
> Layout.append(layout)
> fig = go.Figure(data = data, layout = Layout)
> py.iplot(fig)
>
