chartRadarRadius

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

Implementation notes

Radius-axis rendered as a single line segment from the chart center out to the plot radius at a fixed 60deg angle (not a full symmetric diameter), matching the spec's 'subtle line through roughly one spoke direction... not a fully symmetric cross'. Tooltip now shows the category heading above both series' line-indicator rows.

Status: ported · Reference: shadcn/ui original

chartRadarRadius

// shadcn/ui "charts/radar-radius" recipe — clean-room reimplementation.
//
// The two-series radar chart with an added faint radius-axis reference line
// running from the chart's center out to the edge at a fixed angle (60°,
// no visible tick labels) — a single line, not a full symmetric cross. The
// hover tooltip now explicitly shows the month name as a heading above both
// series' values.
//
// Implemented purely from the block's public functional/visual spec — no
// upstream shadcn/ui source was viewed or copied.
