PlotStyle-DottedLine-always-plots-a-dotted-line

Is it possible to set a LineStyle, let's say Dotted, for a custom indicator through the IndicatorBase class?

I have been trying to override plotstyles with DottedLine or DashedLine like this

CODE:
public override PlotStyles DefaultPlotStyle => PlotStyles.DottedLine;

However, it is always a sold line. When dragging and dropping the custom indicator into my chart I have to set the LineStyle manually to dashed, so I suspect there is a LineStyle feature for a custom indicator that I can set somewhere?
