... to make it easier to get a regression line from List<Coordinates> instead of requiring Coordinates[]

ScottPlot/src/ScottPlot5/ScottPlot5/Statistics/LinearRegression.cs

Lines 14 to 24 in fb3b1c8

public LinearRegression(Coordinates[] coordinates)
{
if (coordinates.Length < 2)
{
throw new ArgumentException($"{nameof(coordinates)} must have at least 2 points");
}
double[] xs = coordinates.Select(x => x.X).ToArray();
double[] ys = coordinates.Select(x => x.Y).ToArray();
(Slope, Offset, Rsquared) = GetCoefficients(xs, ys);
}
