Tooltip | Highcharts

You can customize the chart tooltip using the Tooltip component:

import { Chart, Series, Tooltip } from "@highcharts/react";
export default function TooltipChart() {
  return (
    <Chart>
      <Tooltip>{"<b>{series.name}</b>: {point.y} USD"}</Tooltip>
      <Series data={[3, 4, 1, 5, 2]} />
    </Chart>
  );
}

The Tooltip component accepts all tooltip API options as props. The tooltip format can be passed as children.

Note: For a more structured tooltip, it's a good practice to use the data-hc-option attribute to map child elements to specific tooltip options. See the Option binding documentation for more details.
