Radar Graph styling is not applied

Setting a style e.g,
RadarSeries series = chart.addSeries("data", data, labels);
series.setLineWidth(5);
The line width is not applied as the BasicStroke is not used. It is missing in PlotContent_Radar doPaint.

Yes, it may be that the developer is missing. In the PlotContent_Radar.doPaint(Graphics2D g) method, forget to set g.setStroke(series.getLineStyle());
There may be very few people who care about this feature and have been discovered by you.
