<!-- Answer --> Adding the `dimensions` field (which maps to the `groupby` parameter in Superset) changes how series keys and tooltip keys are constructed in mixed charts. This shift exposes a known bug in the tooltip rendering logic: when dimensions are present, the mapping between series keys and their formatters becomes fragile, leading to errors like incorrect value formatting (e.g., numbers shown as percentages) and mismatched metric labels in the tooltip. This is a regression in recent Superset versions and is not specific to your setup—others have reported the same issue after adding dimensions or groupby fields to mixed charts. There is no official fix yet, but the root cause is the inconsistent key mapping in the tooltip formatter logic when dimensions are used.
