Hi,

thanks for the reply.

your solution worked for me.

first i assigned the key property for the chartlayer apperence

chartLayerAppearance.Key = "LineChartLayer";

than in FillSceneGraph event i checked

if (dataPoint.Layer.LayerID.Equals("LineChartLayer"))
{......... 

Hi utkarsh_bandekar,

Thank you for your reply.

Below is some sample code for accessing the layer id of a particular dataPoint:

((Infragistics.UltraChart.Core.Primitives.Primitive)(dataPoint)).Layer.LayerID

Please let me know if this helps.

hello Petar,

thanks for your reply.

i am using FillSceneGraph to highlight low/high datapoint.

i am facing one problem in FillSceneGraph.

i have a composite chart which has two chart layers with line chart and area chart resp.

the below event highlights low/high point in both charts line as well as area.

i want to highlight only in line chart.

void ultraChart_FillSceneGraph(object sender, Infragistics.UltraChart.Shared.Events.FillSceneGraphEventArgs e)
        {
            UltraChart ultraChart = sender as UltraChart;
            if (ultraChart != null)
            {
                PrimitiveCollection symbols = new PrimitiveCollection();
                foreach (Primitive p in e.SceneGraph)
                {
                    
                    Polyline polyline = p as Polyline;
                    if (polyline != null)
                    {
                        foreach (DataPoint dataPoint in polyline.points)
                        {
                            NumericTimeDataPoint numericTimeDataPoint = dataPoint.DataPoint as NumericTimeDataPoint;
 
                            if (numericTimeDataPoint != null)
                            {
                                Symbol symbol;
                                
                                        if (numericTimeDataPoint.NumericValue == Maxvalue)
                                        {
                                            symbol = new Symbol
                                                         {
                                                             icon = SymbolIcon.Circle,
                                                             iconSize = (SymbolIconSize) 7,
                                                             PE = {Fill = Color.FromArgb(0, 50, 205, 50),
                                                                   StrokeWidth = 0,
                                                                   Stroke = Color.Transparent
                                                             },
                                                             point = dataPoint.point
                                                         };
                                            symbols.Add(symbol);
                                        }
 
                                        if (numericTimeDataPoint.NumericValue == Minvalue)
                                        {
                                            symbol = new Symbol
                                                         {
                                                             icon = SymbolIcon.Circle,
                                                             iconSize = (SymbolIconSize) 7,
                                                             PE = { Fill = Color.FromArgb(0, 255, 48, 48) ,
                                                                StrokeWidth = 0,
                                                                 Stroke = Color.Transparent
                                                             },
                                                             point = dataPoint.point
                                                         };
                                            symbols.Add(symbol);
                                        }
 
                                }
                            }
                        }
                        break; //since chart type cannot be known, it is assumed the 1st collection is of line chart
                    }
                }
                e.SceneGraph.AddRange(symbols.ToArray());
            }
