gp-coords-widget 0.1.0

Continuous parallel coordinates widget for GP / function distributions

gp-coords-widget

Continuous parallel coordinates widget for visualising distributions over functions — GP priors, posterior samples, ensemble forecasts.

Install

pip install "gp-coords-widget @ git+https://github.com/josephsmann/gp_widget.git"

Usage

import marimo as mo
from gp_coords_widget import ContinuousParallelCoords

widget = mo.ui.anywidget(ContinuousParallelCoords(
    x_values,   # list of floats — the shared input grid
    y_samples,  # list of lists — shape (n_samples, len(x_values))
))
widget

Interactions

• Click in the plot → add a constraint at that (x, y)
• Drag body → reposition the constraint (horizontal = x, vertical = y-shift)
• Drag top/bottom handle → resize the y-range
• Double-click → remove the constraint

widget.filtered_indices — indices of samples consistent with all constraints.
