jpcontourf

Draw filled contours directly from scattered (x, y, z) points. Like jpcontour, but produces colored bands instead of lines.

Based on: Axes.contourf, 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 usual filled-contour styling: levels, cmap, vmin, vmax, extend, alpha.

Example

- name: filled
  data:
    - source: df
  axes: ax
  method: jpcontourf
  coordinates:
    x: {expr: xx}
    y: {expr: yy}
    z: {expr: LogL}
  style:
    interp: {method: natural_neighbor, bin: 300}
    levels: 50
    cmap: jarvis_rainbow2_r
  colorbar: axc

Notes

• For a continuous (non-banded) field from scattered points, use jpfield.
