Charts: Routing to a secondary in the replica set

Is there a planned feature in charts to allow all/some chart queries to be routed to replica members other than the primary? Seems like this could be a common use case for larger data sets.

Charts already uses the secondary read preference by default. You can change it per deployment (e.g. to use analytics nodes) on the Data Sources Page.

@tomhollander - We have the default setting for charts with readPreference = Secondary. I have a related question. Should the query that serves the data to a chart be send for execution to all secondary nodes? or one?
