Hello, I've read on the home page that jopenchart performs "polynomial and spline interpolation of data sets and linear regression of measured data".
I need some code to perform spline interpolation but I only have found the method interpolate in the ChartUtilities class.
The javadoc of this method says it applies the Neville's interpolation algorithm.
Any one knows where's the code that performs the spline interpolation?

Thanks in advance
Fernando
