[Feature] add legendhovered event
See original GitHub issueWhat problem does this feature solve?
This feature is related to “Can´t display tooltip on chart legend (Echarts)”. The problem basically is that there seems to be no way to show a tooltip for the legend item. In our case some of the items are often lengthy and do not fit:
Documentation has entry for legend.tooltip, but it doesn’t seem to do anything. I’m not sure if it’s a bug with implementation or documentation. Either way would be great to have it working or at least to have a legendhovered event to show the tooltip manually, as @Ovilia suggested here.
What does the proposed API look like?
Have a legend.tooltip working or legendhovered triggered when legend item is hovered. In the latter case listener should receive all details about currently hovered legend item.

@jayarjo It worked! So I set
positionin thetooltipproperty, it also takes effect for the legend.tooltip property. So…I thought they are the same! But it does create a tooltip for the legend. Not sure if I made it clear. Anyway, thanks!I’m trying to make the legend tooltip match the item tooltip, but the
legend.tooltip.formatterdoes not receive all of the parameters that thetooltip.formatterreceives. It receives thename, but not thevalue.Is there a way to accomplish this?
