juxt 0.4.0

Fast desktop tool for navigating N-dimensional hypercubes of geospatial plots

juxt

juxt is clipped from juxtapose (Latin juxta, "beside") and shares its meaning with παραβολή (parabolē, "placing beside") — the Greek root of both parable and parabola.

juxt is a fast desktop tool for visually comparing geospatial plots across multiple parameter axes. Define axes (sensor, date, overpass, source, …) and flip through the resulting image hypercube with keyboard navigation.

Install

pip install juxt

Quick start

python make_sample.py          # generate 24 synthetic test images
juxt sample_config.yaml

Config

Template mode

template: "plots/{sensor}_{date}_{overpass}_{source}.png"
axes:
  sensor:   [ASCAT, SMAP, SMOS]
  date:     [2024-03-15, 2024-03-16]
  overpass: [AM, PM]
  source:   [L2, L3]
keys:
  s: sensor
  d: date
  o: overpass
  r: source

Auto-discover mode

discover:
  directory: plots/
  separator: "_"

Scans filenames, splits on the separator, and treats any column with more than one distinct value as an axis. On first run, axes are named axis_0, axis_1, … — rename them by switching to template mode.

Navigation

Key	Action
← / →	cycle the horizontal axis
↑ / ↓	cycle the vertical axis
letter key	focus that axis — most recent becomes horizontal, previous becomes vertical
Space	toggle between current and previous position
Home / End	jump to first / last value on the focused axis
1–9	jump to the Nth value on the focused axis
f or double-click	fit image to window
0	reset zoom to 100%
h	toggle status overlay
scroll wheel	zoom (anchored under cursor)
drag	pan

The status overlay (top-left) shows the current coordinate values and which axes are bound to the arrow keys.
