useChart must be used within a <ChartContainer />

Error message

useChart must be used within a <ChartContainer />

What it means

Identical contract to [152] but in the `base` style registry. `useChart` reads `ChartContext`; chart parts rendered outside `<ChartContainer>` throw so config is never null.

Solutions

1. Wrap chart parts in `<ChartContainer config={cfg}>` from the `base` style import path.
2. Always pass a `config` prop to ChartContainer.
3. Decorate tests/stories with `<ChartContainer>`.

Example fix

// before
<ChartTooltip />
<ChartContainer config={cfg}>...</ChartContainer>

// after
<ChartContainer config={cfg}>
  <ChartTooltip>
    <ChartTooltipContent />
  </ChartTooltip>
</ChartContainer>

render(<ChartContainer config={cfg}><ChartTooltip><ChartTooltipContent/></ChartTooltip></ChartContainer>) // base style imports

import React from "react"
import { ChartContext } from "@/registry/bases/base/ui/chart"
const insideChart = () => React.useContext(ChartContext) != null

try { useChart() } catch (e) { if (e.message.includes("<ChartContainer />")) {/*wrap in ChartContainer*/} throw e }

When it happens

Trigger: Mounting `<ChartTooltipContent />` / `<ChartLegendContent />` outside `<ChartContainer config={...}>` when importing from the `base` style.

Common situations: Using the `base` style and relocating tooltip/legend outside the container; tests of individual parts.
