Aliases: sp.build_stackplot3d_chart(), sp.stackplot_3d(), sp.stackplot3d_chart(), sp.stackplot3d_family(), sp.stackplots3d().
Description
sp.stackplot3d() is the 3D twin of sp.stackplot(): every one of the 5 stackplot variants has a 3D form, selected with the same variant keyword and fed with the same series. Every series is a sloped band whose floor is the running total of the series below it, reusing the same shared 2D stacking maths (bottoms/tops per point) as the 2D chart so the silhouette matches exactly.
Variants
| Variant | Aliases | Uses | 3D form |
|---|---|---|---|
basic | default, classic, stacked | x_labels, series | Series stacked from the floor, each band’s bottom the running total of the ones before it. |
streamgraph | stream, silhouette, themeriver | x_labels, series | The same stack centred around zero instead of the floor, so it reads as an organic flowing ribbon. |
normalized | percent, hundred_percent, share | x_labels, series | The stack normalised so every point’s total reads exactly 100%. |
radial | polar, radar_stack, circular | x_labels, series | The stack wrapped around a ring: each x position becomes an angle, with a vertical stack of series rising from it. |
ribbon | glow, smooth, flow | x_labels, series | The same floor-anchored stack with smoothed, spline-interpolated edges. |
Data
x_labels name the points and series (with series_names) gives the stacked value lists.
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.
