Smooth Line Tension

Tension of smooth lines can be adjusted for some smoothing strategies. Low tensions lead to ‘overshoot’ and high tensions produce curveswhich appear more like straight lines.

Scatter.cs

ScottPlot.Plot myPlot = new();

double[] xs = Generate.RandomWalk(10);
double[] ys = Generate.RandomWalk(10);

var mk = myPlot.Add.Markers(xs, ys);
mk.MarkerShape = MarkerShape.OpenCircle;
mk.Color = Colors.Black;

double[] tensions = { 0.3, 0.5, 1.0, 3.0 };

foreach (double tension in tensions)
{
    var sp = myPlot.Add.ScatterLine(xs, ys);
    sp.Smooth = true;
    sp.SmoothTension = tension;
    sp.LegendText = $"Tension {tension}";
    sp.LineWidth = 2;
}

myPlot.ShowLegend(Alignment.UpperLeft);

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