`jpfield`

Render a continuous pseudocolor field from scattered (x, y, z) points. Jarvis-PLOT interpolates the points onto a regular grid and draws them with pcolormesh — the smooth counterpart of jpcontourf.

Based on: Axes.pcolormesh, preceded by scattered-data interpolation, rendered in axes-fraction space.

Axes: rectangular (ax) and ternary (axtri).

Coordinates

Key	Required	Meaning
`x`	yes	Scattered point x
`y`	yes	Scattered point y
`z`	yes	Scattered point value

Style

Interpolation under style.interp (method, bin, nx, ny, xlim, ylim, nan_policy) — see jpcontour — plus the pseudocolor styling: cmap, vmin, vmax, norm, alpha. Contour-only keys such as levels/colors are ignored.

Example

- name: field
  data:
    - source: df
  axes: ax
  method: jpfield
  coordinates:
    x: {expr: xx}
    y: {expr: yy}
    z: {expr: LogL}
  style:
    interp: {method: natural_neighbor, bin: 400}
    cmap: jarvis_rainbow2_r
    vmin: -50
    vmax: 0
  colorbar: axc

Notes

Undefined regions (outside the convex hull) stay masked.
If you have already gridded the field, use pcolormesh directly.
