How to reset hoverData?

I am currently playing around hovering over 1 chart and updating another. I am able to get the data from the hover chart as needed, and updating the second chart.

What I want is when the user no longer hovers the chart, the 2nd chart should reset back to its normal state.

For example, the first chart shows data by Month (Jan, Feb, March… Dec). The 2nd chart initially shows full year data - I want it to update to a specific month when hovered, which works. I want the 2nd chart to reset to full year once the user no longer hovers over any bars from the first chart.

Is it possible to “reset” the hoverData information?
