Interactive Area Chart

Q: Does it animate when the range changes?

The definition is rebuilt from the selected range (useMemo, computed, $derived or createMemo), and TanStack tweens the areas to their new shape over 400ms. Under reduced motion they snap into place.

Q: Why does the select disappear on phones?

Its trigger has hidden sm:flex, as in shadcn/ui's original, so below the sm breakpoint the chart shows the full 90 days. Remove hidden to keep the select on small screens.

Q: How do I plot my own dates?

Give each row an ISO date (2024-04-01) and the two values. The label formatters parse it with new Date(), which reads a day-only date as midnight UTC: format with timeZone: "UTC" or readers west of UTC see the day before.

Three months of daily desktop and mobile visitors as stacked gradient areas, with a select for the last 90, 30 or 7 days. For Svelte.

About

This is the dashboard chart: a long daily series where the reader picks the window. Use it when one view has to serve both the quarter and the last week. For two series people compare one at a time, the Interactive Bar Chart switches between them instead.

Desktop and mobile stack as smooth curves with gradient fills, under date labels spaced so they don't collide. A select in the header filters to the last 90, 30 or 7 days, the tooltip shows the date, and a legend sits under the plot.

Usage

<script lang="ts">
import ChartAreaInteractive from "@/components/charts/chart-area-interactive.svelte";
</script>

<ChartAreaInteractive />

Customize

The range lives in state (React useState, a Vue ref, Svelte $state or a Solid signal), and the rows are filtered by it before they reach the marks.
The definition is derived from the range (useMemo, computed, $derived or createMemo), so it's rebuilt only when the select changes.
ChartTooltipContent gets a labelFormatter that prints the hovered date as Apr 10, and the dot indicator.
The gradients are the Gradient Area Chart's: one per series in the definition's gradients, used as url(#<id>) fills.
ChartContainer has aspect-auto h-[250px] w-full in its class: a fixed height at the card's full width.

FAQ

How does the range filter work?

The rows run from April 1 to June 30, 2024. The select's value (90d, 30d or 7d) sets how many days to count back from June 30, and only the rows from that date on reach the chart. With live data, count back from today or ask your API for the range.

Does it animate when the range changes?

The definition is rebuilt from the selected range (useMemo, computed, $derived or createMemo), and TanStack tweens the areas to their new shape over 400ms. Under reduced motion they snap into place.

How do I plot my own dates?

Give each row an ISO date (2024-04-01) and the two values. The label formatters parse it with new Date(), which reads a day-only date as midnight UTC: format with timeZone: "UTC" or readers west of UTC see the day before.

How do the date labels avoid overlapping?

TanStack thins colliding tick labels by default, so only some of the 90 dates get one; tickLabels: { thin: { minGap: 32 } } on the x axis widens the gap, like Recharts' minTickGap. A tick format prints each as Apr 10.

Can I use it without a mouse?

Yes. The select is a regular form control, reached with Tab before the chart. In the chart, the arrow keys step one day at a time and Home and End jump to the first and last day of the range.
