Hi,
See this example: https://jsfiddle.net/dizzy0ny/3ukcexvh/277/
couple of issues:
1. if you however over a way with a scatterplot point, it does not show in the tooltip
2. the scatter plot points also fade while hovering over candles
2. if you do focus on a scatter point, the tooltip does show, but only the tool tip for the scatter point and the dates are still in epoch it seems, unformatted.
