[QUESTION] No format prop for LineChart.Tooltip

[shivansal]

Hi. I am trying to customize the value shown when pressing down on a point in the graph. In specific, I want to add a dollar sign in front of the value to indicate a currency value. Please let me know if anyone has been able to accomplish this or if I am looking at the wrong prop object. Thank you.

Hey @shivansal yes that's indeed possible to change the formatting on the cursor tooltip. You can do so as follows:

  const format = ({ value }) => {
    'worklet'
    return `$${value}`
  };

    return (
        ...
            <LineChart.Tooltip textProps={{ format }}  />
        ...
    );
