Plotly Express 和 Python 上的变量 ID 子图

Question

I have plot like this:

var_names = [i for i in test_df.variable.unique()]
var_names.sort()

fig = px.scatter(test_df, x='date', y='value', color='variable', category_orders={'variable': var_names},
                template="ggplot2", title='Median of access',
                 labels={'value': 'Median of access on the week', 'date': 'Week'}
                 ).update_traces(mode='markers+lines')
fig.show()

And my dataframe is:

test_df = pd.DataFrame({
        'ID':list('aabdee'),
        'date':['2020-03-22', '2020-03-22', '2020-03-29', '2020-03-22','2020-03-22', '2020-03-29'],
         'B':[1,0.5,4,5,5,4],
         'C':[7,8,9,4,2,3],
         'D':[1,3,1,7,1,1],
         'E':[5,3,6,9,2,4]
})
test_df = test_df.melt(['ID', 'date']).  

I want to run the code just once and build different subplots depending on the ID, like if each graph in the picture below were corresponding to the variables of a specific ID.
I tried with 'add trace' as is on the doc, but if I do this I have to copy and paste the code each time filtering by the ID.

Thank you a lot!

In the end was super simple, the problem is that the documentation of plotly express is not so easy to find.

So, you can put the variable facet_col='ID' on your px.scatter(...) and it works:).
