 With the new version 1.x.y the original curve computation (nergal.dev's code) has been replaced by a new algorithm which computes hermite splines.
 In general the result should be closer to the data however the old implementation is still accessible through the legacyOverride option.
 
-The approximation with local third-degree polynoms solves some existing issues. The problematic parameters curvePointFactor and fitPointDist are both gone
-and I hope that the new nrSplinePoints needs less manual adjustment (basically only wiht zoom) and is easier to understand.

 The old fit option has been replaced with monotonicFit, which if set, enforces the use of the Fritsch-Carlson method (anti wiggle no overshooting / undershooting).
