  @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.

  @bkshn,

  You can add 2 dummy datapoints in the hidden region of the doughnut chart and use their indexlabels to show the minimum and maximum value of the gauge as shown in the code snippet below:

  var data = {
      type: "doughnut",
      indexLabelPlacement: "inside",
      innerRadius: "60%",
      dataPoints: [
        {
          y: 1,
          indexLabel: gauge.maximum + "",
          color: "transparent"
        },
        {
          y: gauge.maximum - 2,
          color: "transparent",
          toolTipContent: null
        },
        {
          y: 1,
          indexLabel: "0",
          color: "transparent"
        },
        gauge.data,
        gauge.unoccupied,
     ],
  };

  Please check this JSFiddle for a working example.
