Hi Sara

See the Custom Labelprovider documentation. This shows you how you can format labels as anything you want (complete control over label formatting).

You can override label formatting as simply as this:

xAxis.labelProvider.formatLabel = (dataValue, format) => {
    const unixDateStamp = dataValue;
    return new Date(unixDateStamp * 1000).toLocaleDateString("en-GB", {
        month: "numeric",
        year: "numeric",
        day: "numeric"

The label value is stored as a unix timestamp so you just need to format Unix Timestamp to HH:MM:SS.ssssss.

A function like this can convert a unix timestamp to milliseconds

export const formatUnixDateToHumanString = (unixTimestamp: number): string => {
    const date = new Date(unixTimestamp * 1000);
    const hours = date.getHours();
    const minutes = date.getMinutes();
    const seconds = date.getSeconds();
    const milliseconds = date.getMilliseconds();

    if (isNaN(hours) || isNaN(minutes) || isNaN(seconds)) { 
        return ""; 

    return `${hours}:${minutes}:${seconds}:${milliseconds}`;

Let me know if this helps

Best regards
