Threshold Day Chart

Install

Or by hand, in a Next.js project with shadcn set up. It writes components/pastetaste/threshold-day-chart.tsx.

Install the pastetaste component "Threshold Day Chart" (threshold-day-chart) into this Next.js project and use it.

What it is: A 24-hour area chart whose area turns to the alert colour above a threshold, with pointer scrubbing, an interpolated tooltip, event markers with chips and stat tiles.

Before you place it, ask me (one short message, in my language; "skip" = sensible default): which page and section it goes in, my brand colour (hex), the text, labels or images it should show, and whether I want my logo or my own copy in the demo content. Then:

Steps:
1. If the project has no components.json, run: npx shadcn@latest init -y -d. Then run: npx shadcn@latest add https://pastetaste.com/r/threshold-day-chart.json
   (it writes components/pastetaste/threshold-day-chart.tsx; install any npm packages it reports).
2. Import it: import { ThresholdDayChart } from "@/components/pastetaste/threshold-day-chart" (check the file for the exact named export).
3. Put it where it fits on the page I name, keep the rest of the page untouched, and pass props for my colours instead of editing the installed file.
4. It does not depend on Tailwind; colours come from CSS variables (--pt-*) or props.
5. It supports prefers-reduced-motion with a still state; do not remove it.

Props (all optional unless the type has no default):
- points: [number, number][] — [hour 0–24, value] pairs, sorted.
- events: { x: number; label: string }[] = [] — Moments marked on the curve and as chips.
- stats: { label: string; value: string }[] = [] — Tiles under the chart.
- threshold / thresholdLabel: number / string = 1000 — Value where the area turns to the alert colour, and its label.
- min / max / ticks: number / number / number[] = 400 / 1600 / 400..1600 — Value range and grid lines.
- unit / overNote: string = ppm / alert on — Tooltip unit and the note added at or over the threshold.
- label: string = Value over 24 hours — Accessible description.
- alert: string — Alert colour override.
- className / style: string / CSSProperties — On the root.

Then run the dev server, check it in the browser at desktop and mobile width, and tell me the page URL.
