Vector Field Map 3D

Signature

sp.vector_field_map3d(title, lats=None, lons=None, u=None, v=None, *, variant="arrows", orientation3d="iso", scene="default", theme="none", zone=None, max_points=None, bg_color="#1a1a2e", width=1200, height=650, x_label="", y_label="", z_label="", **kwargs) -> Chart

Aliases: sp.build_vector_field_map3d_chart(), sp.vector_field_map_3d(), sp.vector_field_map3d_chart(), sp.vectorfieldmap3d().

Description

sp.vector_field_map3d() is the 3D twin of sp.vector_field_map(): all 3 vector-field variants share the same 3D form, selected with the same variant keyword. Every grid point (lats/lons) gets a short segment pointing toward u/v, its thickness, tone and height all following the vector’s own magnitude.

Variants

VariantAliasesUses3D form
arrowsquiver, wind, basic, defaultlats, lons, u, vOne direction segment per grid point, thickness and height following its magnitude.
streamlinesstreamline, flow, particleslats, lons, u, vThe same segments as arrows; the 2D chart’s flowing-particle styling has no separate 3D form.
wind_barbsbarbs, meteorological, station_modellats, lons, u, vThe same segments as arrows; the 2D chart’s meteorological barb styling has no separate 3D form.

Data

lats/lons position each grid point and u/v give its vector’s eastward/northward components.

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.

theme="deluxe"
theme="prism"
theme="aurora"
theme="inferno"
theme="frost"
theme="glow"
theme="glass"
theme="neon"
theme="cosmic"

Auto-scaling zone

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.

Parameters

Returns

Chart object with an .html property and a .show() method.
