Curvature graph question

Rhino
1

Shouldn’t all the spacing of the CurvatureGraph of a circle be even??Too small to care about? Is it generated based on a setting I have in documents or program settings?

It just caught my eye for a moment.

Spacing of the lines on a curvature graph of a curve depends on the degree, parameterization and knots of the curve as well as the value in the Density field in CurvatureGraph. The spacing does not depend on the arc length or angle.

The spacing in your illustration is consistent with additional knots on the right side of the circle.

When I move the circle to a different area, the graph changes. Does that mean the circle is changing?

With an “out of the box” circle or cylinder, the curvature graph’s hair line spacing should always be uniform, unless you mess with the CVs or edit points.

I tried another circle, and it looked fine - I must have hit a control point somewhere..
