Each segment has an assigned label. Chart uses a custom label layout algorithm to make sure no labels overlap and are distributed nicely. It is essentially a simple line chart with added 3D look. Data is analyzed by building virtual surface cells and resolving ambiguities arising at the break points of the surface. The resulting surface appears smooth and clear.
Surface is rendered using separate palettes for top and bottom sides.
Palette colors are shaded using built-in lighting model. It has all features of a full version, but draws a trial version banner in the corner of each view. Current version of the package can be downloaded from the downloads section .
