[LineChart]: in the new scaleType: time, I can't get multiline tooltips to show up for my data, it appears from the demo data that they only show up if the x exactly matches one of the gridlines

Issue description

You can see this limitation in the demo data page, by hovering over a non-gridlined datapoint

Versus a gridlined datapoint:

I don't think the gridline tooltips are working at all.

On a continuous axis you need a continuous tooltip, because you will still have a real domain within the gridlines that need to be addressed.

(Refer to the Intermediate Value Theorem - https://www.mathsisfun.com/algebra/intermediate-value-theorem.html)

I suggest the tooltip persisting onHover at any point within the grid.

If the developer knows that there is a lack of relation between the points on the graph, they could switch to the gridline tooltips through some configs.

@theiliad I second the need for the fix. All my time series data points are aligned but not with gridlines and tooltip only shows one data point.

Is it possible to have gridlines configured along the datapoints? It would be nice to include timestamp as part of tooltip for time series charts

This issue is solved by #478

Russel, this image shows the application of the updated tooltip to this specific case
