We’re actually writing now some code to perform this interpolation for you for our next release. The new API will become:
// with interpolate = false, hit-tests data-points. With true, hit-tests the actual line (or area for Mountain, etc) var hitTestResult = FastLineRenderableSeries.HitTest(Point pt, bool interpolate);
This APi will then be used in our SeriesSelectionModifier to improve the selection on click of all series types.
How quickly do you need this feature?
Update: Using SciChart v3.0 APIs
We now have a number of APIs which will allow you to do Hit-Testing operations, such as getting a notification of mouse-hover, mouse-click selection of a series.
