How can I do this?

Hi Park, 

 

Greetings from the team at Syncfusion. We have looked over your query and can tell you that you can now change the data labels, using the onDataLabelRender function. We can assign the empty text to all other data labels by checking the point index, and so just the last data label alone is visible. We have attached the sample for your reference ad kindly make use of it. For your required scenario, we have already logged a feature request to represent the last data alone in the axis labels and we cannot provide a date for this because it is not on our forthcoming scheduled list. But we can promise you that it will be included in one of our upcoming versions. The status of this feedback can be tracked using the feedback link below.

onDataLabelRender: (DataLabelRenderArgs args) {
  if (args.pointIndex != args.dataPoints.length - 1) {
    args.text = '1';
  } else {
    args.text = "test";
  }
},
