Few things wrong, the onHover
does not belong in the hover
sub options part, dont even think there is a hover sub options part. Also the event is not an array but an object, you want to have the second parameter which contains all the active elements.
Also the legend needs to be configured in the plugins
section. Also doesnt make sense to disable the legend and use the onHover
and onLeave
callbacks
