chartRadarMultiple

A Charts block/component from shadcn/ui — clean-room reimplemented for Domphy (see methodology). Call chartRadarMultiple() with no arguments for a working demo, or edit the code below live.

Implementation notes

Same SVG/tooltip engineering approach as chartRadarDefault. Tooltip renders both series' values with a thin line-style indicator and no month heading (interpreted from the spec's own contrast against chartRadarRadius, which explicitly says it 'now' adds the heading 'rather than only showing values').

Status: ported · Reference: shadcn/ui original

chartRadarMultiple

// shadcn/ui "charts/radar-multiple" recipe — clean-room reimplementation.
//
// Two overlapping radar series (desktop/mobile) plotted on the same
// hexagonal axis: the first stays translucent (~60% opacity) while the
// second renders essentially opaque, so it visibly pokes through the first
// wherever the two shapes overlap. Hovering lists both series' values for
// the nearest month, each row marked with a thin line-style indicator.
//
// Implemented purely from the block's public functional/visual spec — no
// upstream shadcn/ui source was viewed or copied.
