Gauge Angular Range

By default gauges are full circles (360 degrees) but smaller gauges can be created by customizing the gauge size.

RadialGauge.cs

ScottPlot.Plot myPlot = new();

myPlot.Add.Palette = new ScottPlot.Palettes.Nord();
double[] values = { 100, 80, 65, 45, 20 };

var radialGaugePlot = myPlot.Add.RadialGaugePlot(values);
radialGaugePlot.MaximumAngle = 180;

myPlot.SavePng("demo.png", 400, 300);
