This page documents HiPlot’s core Parallel Plot display, rendered by src/parallel/parallel.tsx.
Each datapoint is drawn as a polyline across column axes:
One axis per visible parameter
One line per filtered datapoint
Color driven by the active color-by setting
This is the primary surface for slicing and filtering high-dimensional data.
Brush axis ranges: drag vertically on an axis to filter by value interval.
Clear brush: click/tap outside the active brush on that axis.
Reorder axes: drag axis headers left/right.
Invert axis: toggle axis direction from the label/context menu.
Hide axis: remove columns from the display.
All of these interactions feed into HiPlot’s shared filtered/selected state, which updates the other displays (XY, Distribution, Table).
The parallel plot uses:
Canvas layers for fast polyline drawing
SVG for axes, labels, and brushes
This allows large-row rendering without losing axis/interaction fidelity.
Display-level settings are provided through exp.display_data(hip.Displays.PARALLEL_PLOT).
Common options:
order: explicit column order
hide: columns hidden by default
invert: columns inverted by default
categoricalMaximumValues: auto-hide threshold for very high-cardinality categorical axes
For the full schema, see docs/plugins_reference.rst.
Columns with a single effective value can disappear unless you force a range in parameter definitions.
High-cardinality categorical columns can be hidden automatically by categoricalMaximumValues.
Hidden/inverted/order state is persisted via persistent state and restored on reload.
