Width

The width distribution along the limb defines its side-to-side shape, which is shared by all layers. It is defined by a table of relative length and width values. Each row specifies a position along the limb (from 0% to 100%) and the corresponding width of the limb at that point. A smooth curve (a monotone cubic spline) is fitted through these values to create the final width distribution, which is displayed in the Graph panel. The plot’s context menu offers additional options, such as showing or hiding control points or adding an overlay image.
