@bkshn,

A doughnut chart does not have axes. If you want to highlight the minimum and maximum values from the datapoint array, you can use subtitles to achieve the same.

If this doesn’t meet your requirement, kindly share a pictorial representation and brief us further about your requirement so that we can understand your scenario better and help you out with an appropriate solution.
