# Chart: Tooltip

> Switch between `dot`, `line` and `dashed` indicators, and hide the label with `hideLabel`. `defaultIndex` on `<ChartTooltip />` shows a point on the first render.

Example: https://hextaui.com/docs/chart/examples/tooltip
Component docs: https://hextaui.com/docs/chart.md

## Add this example

```bash
npx shadcn@latest add https://hextaui.com/r/chart-tooltip.json
```

This adds `components/examples/chart/tooltip.tsx` with the Chart component and the HextaUI theme tokens.
