ComputingAggregationsUpfront doesn't work well

[ptim]

Your first snippet has copied a typo from Chris’ first draft:

See the linked conversation: Sharing a dataframe between plots

Sharing a dataframe between plots

The part in example 2 where you return multiple dfs on their own keys in dictionaries doesn’t seem to work. When we are using a df as the key it complains about “DataFrame is mutable. Cannot be hashed”. If you set the key to be a string, it errors out with a “component.type is undefined” error.

Thanks for reporting @cvax! Yes, this is a typo

   return {
       'df_1': df_1.to_json(orient='split'),
       'df_2': df_2.to_json(orient='split'),
       'df_3': df_3.to_json(orient='split'),
   }
