Scatter Plot with Smooth Lines

Scatter plots draw straight lines between points by default, but setting the Smooth property allows the scatter plot to connect points with smooth lines. Lines are smoothed using cubic spline interpolation.

Scatter.cs

ScottPlot.Plot myPlot = new();

double[] xs = Generate.Consecutive(10);
double[] ys = Generate.RandomSample(10, 5, 15);

var sp = myPlot.Add.Scatter(xs, ys);
sp.Smooth = true;
sp.LegendText = "Smooth";
sp.LineWidth = 2;
sp.MarkerSize = 10;

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