Hover Callback for Area Charts

[ccssmnn]

I'm developing a dashboard with a UI, that is inspired by Apple's Stocks app. When hovering over an area chart, they display the time outside the chart and only the value inside the tooltip.

Chart events don't include a hover event. Only dataPointMouseEnter, which is not triggered for area charts.

Is there any way to receive similar info when data is hovered?

I've also tried to extract hover info inside the custom tooltip method, which doesn't seem to work.
