I have a custom chartmodifier I use for highlighting points on mouseover for my 2D plots and I want to create the same functionality for my 3D scatter plot. However, I can’t get it to work;

for the 2D plot I do

var series = ParentSurface.RenderableSeries[0];
var pt = GetPointRelativeTo(e.MousePoint, ModifierSurface);
double dataPointRadius = 8;
var result = series.HitTestProvider.HitTest(pt, dataPointRadius);

However, it seems that 3D plots don’t have a hittestprovider and that it’s not possible to define a radius for the hit test, so the code becomes

var series = ParentSurface.RenderableSeries[0];
var pt = GetPointRelativeTo(e.MousePoint, ModifierSurface);
var result = series.HitTest(pt);

However, result.IsHit is always false. What am I missing?
