Is there a way to merge two "dictionaries" of values in Graphite? That is to say, I want to start with a series:
AnimalsByCountry
England
Cats
Dogs
France
Cats
Dogs
Birds
And combine them into series:
AnimalsInWorld
Cats // = AnimalsByCountry.England.Cats + AnimalsByCountry.France.Cats
Dogs // = AnimalsByCountry.England.Dogs + AnimalsByCountry.France.Dogs
Birds // = AnimalsByCountry.France.Birds
Sorry if this is an obvious question; I'm new to Graphite and this seems like a simple operation but I can't find any functions to do it in the documentation.
