fix: When component
tooltip.formatter
is not specified, use a specific default formatter, rather than use globaltooltip.formatter
as default.That because the global
tooltip.formatter
is usually configured for series. But tooltip formatter usually can not be shared by series and components (they have different params). So the globaltooltip.formatter
is usually not applicable for component.This PR make a specific default tooltip formatter for component, which returns the item name.
Since
v5.1.0
component tooltip inherits the configs of the global tooltip. So there is no such issue beforev5.1.0
.Fix #14939
