chartTooltipIndicatorLine

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

Implementation notes

Full port. Default date header kept; indicator set to the shared 'line' style (a short vertical color bar) via activityTooltipFormatter's single indicator enum ('dot'|'square'|'line'|'icon'|'none'), the same code path all indicator-style recipes in this family share.

Status: ported · Reference: shadcn/ui original

// shadcn/ui "charts/tooltip" (indicator-line recipe) — clean-room
// reimplementation.
//
// Keeps the default date header, but swaps the round color dot for a short
// vertical color bar/line indicator per series row.
//
// Implemented purely from the block's public functional/visual spec — no
// upstream shadcn/ui source was viewed or copied.
