Feature Suggestion

Please consider adding an option to allow the width of bar in of Radial Chart in Single Gauge Mode to be adjusted. Specifically I'd like to be able to make the bar wider when the chart is shown in single gauge mode. Alternatively have the bar rendered 2 or 2 times the current width when in single gauge mode.

var plt = new ScottPlot.Plot(600, 400);

double[] values = { 100, 80, 65, 45 };

var gauges = plt.AddRadialGauge(values);
gauges.GaugeMode = ScottPlot.RadialGaugeMode.SingleGauge;
gauges.MaximumAngle = 180;
gauges.StartingAngle = 180;

gauges.Width = 50; // new option

plt.SaveFig("radialgauge_single.png");
