Description
sp.parallel3d() is the 3D twin of sp.parallel(): all 9 parallel-coordinates variants share the same 3D form, selected with the same variant keyword and fed with the same rows. Every axis is normalised to its own min/max and laid out along x; every row (one line in the 2D chart) becomes a ribbon on its own depth row, rising and falling in height as it crosses each axis at its normalised value.
Variants
| Variant | Aliases | Uses | 3D form |
|---|---|---|---|
basic | default, classic, lines | axes, series, series_names | One straight-segment ribbon per row, toned by its own index. |
smooth | curved, bezier, spline | axes, series, series_names | The same ribbons, densified into a smooth curve. |
categorical | category, groups, colored | axes, series, series_names | The same straight ribbons, toned by category instead of row index. |
highlight | spotlight, focus, dim | axes, series, series_names | The same straight ribbons; the highlighted row reads bright, every other one dims. |
density | fade, translucent, alpha | axes, series, series_names | The same straight ribbons, all toned down to a uniform faded read. |
arc | bezier_color, smooth_color, colored_bezier | axes, series, series_names | The same smooth, coloured ribbons as smooth. |
ribbon | flow, band, filled_bezier | axes, series, series_names | The same straight ribbons, visibly thicker. |
lineage | movements, timeline_flow, influence, genealogy | axes, series, series_names | The same straight ribbons, toned by category. |
chronicle | category_flow, year_bundle, annual_flow, decade_in_review | axes, series, series_names | The same straight ribbons, toned by category. |
Data
axes names each axis, series gives one row of values per line (one entry per axis) and series_names names each line.
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.
