I have issues when I want to apply a FastBandRenderableSeries AntiAliasing？

Hi，
When I created the FastBandRenderableSeries type, I encountered an aliasing problem. When I used AntiAliasing, it still didn’t work.
There is an example of used code:

List<double> xData = GetData("D:\\x.txt");
List<double> yData = GetData("D:\\y.txt");
List<double> y1Data = GetData("D:\\y1.txt");
XyyDataSeries<double, double> splineBanDataSeries = new XyyDataSeries<double, double>();
splineBanDataSeries.Append(xData, yData, y1Data);
var bandSeries = new FastBandRenderableSeries()
{
DataSeries = splineBanDataSeries,
//Name = id,
StrokeThickness = 1,
Fill = Colors.Transparent,
FillY1 = Colors.Transparent,
StrokeY1 = Colors.LightGray,
AntiAliasing = true,
StrokeDashArrayY1 = new double[] { 5, 1 }
};
sciChart.RenderableSeries.Add(bandSeries);
sciChart.ZoomExtents();
Is there any way to correct this error?
Thank you.
