Chart type is scatterchart.

PointSets in a ScatterChart are all forced to use the same PaintElement/Brush.  in order to color an individual point, you must handle the FillSceneGraph event, loop through e.SceneGraph, find all the PointSets therein, go to the point you want to color, and add a Symbol primitive to the SceneGraph at that same location.

Symbol primitives are just like the points in a PointSet, except they can be independently styled.

private void ultraChart1_FillSceneGraph(object sender, FillSceneGraphEventArgs e)
        {
            PrimitiveCollection primitivesToAdd = new PrimitiveCollection();
            foreach (Primitive p in e.SceneGraph)
            {
                PointSet pS = p as PointSet;
                if (pS != null)
                {
                    foreach (DataPoint dP in pS.points)
                    {
                        if (dP.DataPoint.PE.ElementType != PaintElementType.None)
                        {
                            Symbol symbolOverlay = new Symbol(dP.point, pS.icon, pS.iconSize);
                            symbolOverlay.PE = dP.DataPoint.PE;
                            primitivesToAdd.Add(symbolOverlay);
                        }
                    }
                }
            }
            e.SceneGraph.AddRange(primitivesToAdd.ToArray());
        }

Hi David,

Can you please share some code snippets for the above problem.

I am not sure which property to use to color the points

Thanks

Thank you. I will handle FillSceneGraph event.
