SciChart.Charting Assembly > SciChart.Charting.Model.Filters.SplineInterpolationFilter Namespace > CubicSpline Class : FitAndEval Method
Input. X coordinates to fit.
Input. Y coordinates to fit.
Input. X coordinates to evaluate the fitted curve at.
Optional slope constraint for the first point. Single.NaN means no constraint.
Optional slope constraint for the final point. Single.NaN means no constraint.
Turn on console output. Default is false.
FitAndEval Method
Fit x,y and then eval at points xs and return the corresponding y's. This does the "natural spline" style for ends. This can extrapolate off the ends of the splines. You must provide points in X sort order.
Syntax
public double[] FitAndEval( 
   double[] x,
   double[] y,
   double[] xs,
   double startSlope,
   double endSlope,
   bool debug
)

Parameters

x
Input. X coordinates to fit.
y
Input. Y coordinates to fit.
xs
Input. X coordinates to evaluate the fitted curve at.
startSlope
Optional slope constraint for the first point. Single.NaN means no constraint.
endSlope
Optional slope constraint for the final point. Single.NaN means no constraint.
debug
Turn on console output. Default is false.

Return Value

The computed y values for each xs.
Requirements

Target Platforms: Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
