ClassNonUniformVectorFieldHitTestProvider Hit-test provider for SciChart.Charting.Visuals.RenderableSeries.VectorFieldRenderableSeries when the data series is a SciChart.Charting.Model.DataSeries.NonUniformVectorFieldDataSeries. Scans only the visible (non-culled) arrows for the minimum point-to-shaft-segment distance in O(M) time, where M is the visible count. With heavy culling M << N, giving a significant speedup over an O(N) full scan while also preventing ghost hits on invisible vectors.
ClassOhlcSeriesHitTestProvider  
ClassPolarHeatmapHitTestProvider Provides methods to perform a hit-test of a SciChart.Charting.Visuals.RenderableSeries.PolarUniformHeatmapRenderableSeries at the specific mouse point.
ClassScatterSeriesHitTestProvider  
ClassStackedBoxPlotSeriesHitTestProvider Hit-test provider for SciChart.Charting.Visuals.RenderableSeries.StackedBoxPlotRenderableSeries.
ClassStackedColumnSeriesHitTestProvider

ClassTernaryErrorSeriesHitTestProvider  
ClassTernaryPolygonSeriesHitTestProvider

ClassTernarySeriesHitTestProvider  
ClassUniformVectorFieldHitTestProvider Hit-test provider for SciChart.Charting.Visuals.RenderableSeries.VectorFieldRenderableSeries when the data series is a SciChart.Charting.Model.DataSeries.UniformVectorFieldDataSeries. Uses an O(1) grid-cell formula to identify the nearest arrow, then tests cursor distance against the full arrow shaft segment. Culled (invisible) arrows always return SciChart.Charting.Visuals.RenderableSeries.HitTestInfo.IsHit = false.
ClassVectorFieldHitTestProviderBase Abstract base class for vector field hit-test providers. Provides shared geometry helpers used by both UniformVectorFieldHitTestProvider and NonUniformVectorFieldHitTestProvider.
ClassVolumeCandlestickSeriesHitTestProvider  
Interfaces
 InterfaceDescription
InterfaceIHitTestProvider

The interface to a Hit-Test provider, has methods such as HitTest(Windows.Foundation.Point,double,bool) which return a SciChart.Charting.Visuals.RenderableSeries.HitTestInfo struct with information about the data-point and series at the screen coordinates.

Each SciChart.Charting.Visuals.RenderableSeries.BaseRenderableSeries must have a IHitTestProvider and the default implementation is DefaultHitTestProvider<TRenderableSeries>
