We are using SciChart 2.2.3441
And i need to detect hit only at DataPoint,
RenderableSeries.HitTest(hitTestPoint, true) – works fine!
But RenderableSeries.HitTest(hitTestPoint, 10, false) – always returns IsHit = false. No matter what is hitTestRadius.
See attached project for example

Lal )) I just found the reason.
I created PointMarkerTemplate old school WPF style )) HitTest without interpolation needs PointMarker.Width and PointMarker.Height, and if you created PointMarker like that:

<renderableSeries:FastLineRenderableSeries.PointMarkerTemplate>

</renderableSeries:FastLineRenderableSeries.PointMarkerTemplate>

So PointMarker.Width == Nan and PointMarker.Height == Nan.

Right way is :

xmlns:pm=”clr-namespace:Abt.Controls.SciChart.Visuals.PointMarkers;assembly=Abt.Controls.SciChart.Wpf.2.2″

<renderableSeries:FastLineRenderableSeries.PointMarker>

</renderableSeries:FastLineRenderableSeries.PointMarker>
