Hello. I'm trying to style a series spline to have a thin borderwidth to set it apart from the other splines on the chartview, but no matter what value I set the BorderWidth property to, the spline is the same thickness. Intellisense for BorderWidth mentions that BorderBoxStyle.FourBorders must be used, and the series is normally in SingleBorder, but setting it to FourBorders also didn't help. I also tried to set the BorderDashStyle to dashes, just to see if other property changes would be respected, but the line is still solid. The BorderColor and Spline properties appear to be respected. Any ideas what I'm doing wrong?
Here's the code to create and add the series, as well as a screenshot of the chart. The series in question is to the top (high) red spline.
Thanks!
ScatterLineSeries x3PriceEnvelopeHighSeries = new ScatterLineSeries();
x3PriceEnvelopeHighSeries.XValueMember = "FaceWeight";
x3PriceEnvelopeHighSeries.YValueMember = "x3Price";

x3PriceEnvelopeHighSeries.BorderColor = Color.Red;
x3PriceEnvelopeHighSeries.BackColor = Color.Red;

x3PriceEnvelopeHighSeries.Spline = true;
