Vue PieChart - Access a Label Using the API

NOTE
Before accessing a point label, you must gain access to its series point. You can learn the details in the Access a Point Using the API topic.

To access a point label, call the getLabel() method of its series point. This method returns an object described in the Label section of the API reference.

App.vue
  • <template>
  • <DxPieChart ...
  • ref="pieChart">
  • </DxPieChart>
  • </template>
  •  
  • <script>
  • import DxPieChart from 'devextreme-vue/pie-chart';
  •  
  • export default {
  • components: {
  • DxPieChart
  • },
  • data() {
  • return {
  • label: {}
  • };
  • },
  • methods: {
  • getPointLabel() {
  • const series = this.$refs.pieChart.instance.getAllSeries()[0];
  • const seriesPoints = series.getAllPoints();
  • this.label = seriesPoints[0].getLabel();
  • }
  • }
  • }
  • </script>

Once you access a label, you can, for example, hide or show it by calling the hide() or show() method.

JavaScript
  • label.hide();
  • // label.show();
