What do you mean is doesn't work? I ran the storybook example and hovers on some of the bars and it updates the component state

Hmm, didn't work for me. Let me try again.

Definitely doesn't work for me.

I did yarn install && yarn build && yarn storybook from a fresh new cloned repo

And you then see the actions being logged like in Vega?

@domoritz I'm not sure how to fix this one as vega-lite doesn't issue signal hover. The signal handlers use view.addSignalListeners(signalName, handler) The tooltip does work tho.

Vega-Embed doesn't enable hover handling by default for Vega-Lite. See https://github.com/vega/vega-embed/blob/5042fe105f7ede9500f3cbc4211bfddbd1bc13f8/src/embed.ts#L297. Maybe that's the reason this doesn't work.

Hover handler do not work in vega-lite for me, too. Is there any way to get it done? Thanks.
