  I have seen in other forums that we can use only numbers or date-time in axis, in the bar graph as in the image below. May I know if the feature is limited to that or we can use strings(like labels) in X-axis?

  @shravya,

  In dataPoints, the x value can either be numeric or DateTime object. If you want to show a string as the X-axis label, you can use the label property.

  Kindly take a look at this code-snippet for an example,

  data: [{
    type: "column",
    dataPoints: [
        { label: "One", y: 71 },
        { label: "Two", y: 55 },
        { label: "Three", y: 50 },
        { label: "Four", y: 65 },
      ]
  }]

  Also, take a look at this JSFiddle for an example on column chart with labels.
