@ganttkit/plugin-baseline

Planned-vs-actual comparison. Snapshot a baseline (the plan); the plugin draws a ghost bar behind each task at its planned position, so any slip is visible where the actual bar has moved off the ghost. Scene-hook plugin works with every renderer.

import { createBaseline } from '@ganttkit/plugin-baseline'

const baseline = createBaseline()
engine.use(baseline.plugin)

baseline.capture()  // snapshot the current dates as the plan
// …tasks get rescheduled / dragged; ghosts now show the variance…
baseline.setBaseline({ t1: { start: '2026-07-01', end: '2026-07-10' } }) // or set explicitly
baseline.clear()

API

• createBaseline(initial?) → { plugin, setBaseline, capture, clear, get }
• BaselineEntry: { start, end }; BaselineMap: Record<taskId, BaselineEntry>

Milestones are skipped. Styled via .gantt-baseline (CSS var --gk-baseline).
