Description
sp.ridgeline3d() is the 3D twin of sp.ridgeline(): every one of the 7 ridgeline variants has a 3D form, selected with the same variant keyword and fed with the same samples. Every category becomes a Gaussian KDE curve laid out as a grid of thin columns on its own depth row, all sharing the same value domain so the ridges are directly comparable, the same joy-plot reading as the 2D chart.
Variants
| Variant | Aliases | Uses | 3D form |
|---|---|---|---|
basic | filled, default, single, multi | categories, values | One density ridge per category, rows close enough that tall ridges overlap the row behind them. |
lines | outline, stroke, no_fill | categories, values | The same ridges pressed to a needle-thin profile, a wireframe-like reading of the landscape. |
quartiles | q, qrt, iqr | categories, values | The basic ridges plus a marker plate at each category’s first quartile, median and third quartile. |
mean | average, avg, mean_dot | categories, values | The basic ridges plus a single marker plate at each category’s arithmetic mean. |
rug | ticks, carpet, rugplot | categories, values | Thin ridges plus a small tick at every raw sample’s position along its row. |
heatmap | heat, rainbow, colored | categories, values | The same ridges toned cell by cell on a continuous ramp instead of one flat colour per row. |
spaced | separated, no_overlap, split | categories, values | The same ridges pushed onto widely separated rows, so none of them overlap. |
Data
categories names each sample’s row and values gives its number; every sample sharing a category name feeds that row’s density curve.
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.
