问题 Few days of searching and trying multiple options, but nothing is working actually. With the previous code posted. I've imported all my objects from XAML (all set in variables), I don't know if that would be a problem for that. I don't think since everything else seems to work properly. I just want my Tab2CBB2 to show values depending on the selection of Tab1CBB1. Anyone could help ? (I haven't paste the entire code, neither the paths but you can probably help me with that). Note that those

原文 Draw a smooth curve through a set of 2D points with Cubic Spline I would like to provide you with the code to draw a smooth curve through a set of 2D points with cubic spline. If we have some tabulated function y i =f(x i ) it's easy to get its cubic spline interpolant with some library code. For example, you could use the code from "Numerical Recipes in C, 2-nd Edition" book - proved source of a lot of math algorithms. Cubic spline gives an excellent interpolation in the most cases. Cubic spline is comprised from a sequence of cubic polynomials, so to draw the curve we have to approximate
