Hi

I'm using the built in tfTrend and tfCurveFit functions on my financial chart. Is the a more detailed description of how the control calculates these functions that I can use to describe them more fully to my users?

Thanks,
Ross

Trend Function draws a Line through input Series data points to represent best trend.

The algorithm used to fit the points is a Gaussian Polynomial.

Use the PolyDegree property to determine the number of polynomial coefficients.
