How do I customize the appearance of line Series in my Legend? I have successfully customize the NumericTimeSeries (represented by a line) in the attached LineChart, but am having a hard time figuring out the LegendAppearance. Thanks in advance for any assistance. 

grndElSeries = numTimeSeriesDict["grndElSeries"];

grndElSeries.Label = "Ground Elev. (ft)";

grndElSeries.PEs.Add(new PaintElement(Color.DarkKhaki));

LineAppearance grndElLineApp = new LineAppearance();

grndElLineApp.Thickness = 10;

grndElLineApp.LineStyle.DrawStyle = LineDrawStyle.Solid;

chartGwData.LineChart.ChartComponent.Series.Add(grndElSeries);

chartGwData.LineChart.LineAppearance.Add(grndElLineApp);

But when I do this i get a thick line on the chart but a thin line in the Legend. How do I get the legend line customized?? Thanks VERY much.
