Description
sp.violin3d() is the 3D twin of sp.violin(): every one of the 9 violin variants has a 3D form, selected with the same variant keyword and fed with the same samples. Each category becomes a real Gaussian KDE silhouette sliced into thin discs, its width at every height following the local sample density, exactly the same distribution strategy already used by boxplot3D’s own violin variant.
Variants
| Variant | Aliases | Uses | 3D form |
|---|---|---|---|
basic | simple, kde, density | categories, values | A plain density silhouette per category, no overlay. |
box | with_box, default, vertical | categories, values | The silhouette plus a boxplot-style whisker, box and median slab through its centre. |
quartile | quartiles, lines, iqr | categories, values | The silhouette plus three highlighted plates marking the first quartile, median and third quartile. |
mean | meanline, average, with_mean | categories, values | The silhouette plus a single highlighted plate at the arithmetic mean. |
points | with_points, raw, all_points | categories, values | A slim silhouette plus every raw sample as a small cube aligned on its category’s axis. |
strip | swarm, jitter, stripplot | categories, values | A slim silhouette plus every raw sample scattered sideways by a deterministic jitter. |
horizontal | horiz, h, rotated | categories, values | The basic silhouette turned a quarter-turn onto the depth axis. |
split | paired, back_to_back, mirror | categories, values | Neighbouring categories drawn as mirrored half-silhouettes, back to back. |
half | asymmetric, one_sided, single | categories, values | Only one side of the silhouette is drawn, the other collapsed flat against the centre line. |
Data
categories names each sample’s group and values gives its number; every sample sharing a category name becomes part of that violin.
3D planes
The viewpoint is independent from the variant: orientation3d picks the initial camera plane and applies to every variant; the view always stays draggable.
orientation3d="iso" — Isometric three-quarter view (default).orientation3d="horizontal" — Side-on view, almost at floor level.orientation3d="vertical" — Top-down view from above.orientation3d="front" — Front elevation, nearly flat.3D scenes
scene swaps the environment the columns are drawn in and applies to every variant and every plane.
scene="default" — Each series keeps its own categorical palette color, rendered as shaded 3D bars on a flat grid.scene="terrain" — The data is resampled onto a dense grid and rendered as hundreds of thin colormap-colored columns, forming a continuous mountain-of-bars terrain.scene="tower" — The data is resampled onto a dense field of round skyscraper-like towers instead of boxes, for a city-skyline reading of magnitude.scene="radial" — The data is resampled onto a dense polar grid of rings and wedges radiating from the center, like a 3D radar/sonar sweep of the value field.scene="podium" — The data is resampled onto a dense grid and quantized into stepped terrace levels, like a rice-terrace contour map, to read value bands at a glance.Themes
theme restyles the whole canvas (colour grade and glow) and applies to every variant, scene and plane.

The 3D zone (floor, walls, axes and camera) scales to the elements: its length, width and height follow the extents of the drawn blocks, a minimum floor depth keeps single rows readable, wide scenes are drawn flatter and the camera frames the whole box. The axis ticks read the real data range. Pass zone=[x, y, z] to force the proportions of the box instead; the longest side is normalised to 1.
