File Information
Description

This function is meant to be used for manually smoothing a scattered line (when all other "smooth" functions fail). The idea is to define a spline curve representing the original line. The edge points for the spline line are added by clicking into the axes and are graphically represented by "o" markers. The shape of the spline line can be easily controlled by click&drag on existing edge points. Moving existing markers is possible in between neighbouring edge points. If a marker is moved too close to a neighbour it is deleted. The intial spline line is a straight line connecting the two line ends.

is a straight line connecting the two line ends.

Brilliant little tool! Really handy to fit curves manually with very scattered data.
