Note that I am attempting to line this SciChart up with another one below, and that the XAxis range is provided by that other SciChart. This would be just a tester version of my Rollover template. And an example of me styling one of the Scatter series. The RolloverMarker here is transparent, as I'd like the RolloverTemplate tooltip to display on hover, but necessarily the Marker on each of the Circles. Perhaps you can suggest a better way to do this?
