Parallel coordinates#32028
Conversation
Add a new parallel coordinates plotting module for visualizing multi-dimensional data. Each dimension is drawn as a vertical axis and data points are connected as polylines across the axes. Supports numpy arrays and pandas DataFrames, class-based coloring, custom colormaps, and style customization.
Add parallel_coordinates to the Axes class via _make_axes_method, following the same pattern as stackplot, streamplot, and table. Also adds the corresponding type stub.
Add the parallel_coordinates function to pyplot as a thin wrapper around Axes.parallel_coordinates. Register it in boilerplate.py so it appears in the generated pyplot section.
Add unit tests covering basic usage, class_column, color/cmap, style parameters, edge cases (1D data, 1-column data), and DataFrame input.
Add a gallery example showing parallel coordinates with three synthetic clusters in 4-dimensional space, colored by cluster label.

Hi, you committed your deepseek session and didn't fill out the template, so not sure if there's a human in the loop. Also, adding parallel coordinates needs a discussion, so please explain what motivated this PR. |
