Hello Chris,

Maybe one possible approach to achieve desired behavior could be if you are using for example:

myLegend = new CompositeLegend();
myLegend.ChartLayers.Add(myColumnLayer);
myLegend.ChartLayers.Add(myColumnLayer2);
myLegend.ChartLayers.Add(myColumnLayer3);
myLegend.ChartLayers[1].LegendItem = LegendItemType.Auto;
myLegend.Bounds = new Rectangle(0, 85, 15, 15);
myLegend.BoundsMeasureType = MeasureType.Percentage;
myLegend.PE.ElementType = PaintElementType.Gradient;
myLegend.PE.FillGradientStyle = GradientStyle.ForwardDiagonal;
myLegend.PE.Fill = Color.CornflowerBlue;
myLegend.PE.FillStopColor = Color.Transparent;
myLegend.Border.CornerRadius = 10;
myLegend.Border.Thickness = 1;

Please take a look at the attached sample for more details and let me know if you have any questions
