JavaScript/jQuery PieChart - Show and Hide a Point

The PieChart provides an API for showing and hiding a series point at runtime. This API is commonly used to show or hide a series point when a user clicks the chart legend. You need to handle the legendClick event as shown below to implement this scenario. The isVisible(), hide() and show() are Point object methods.

JavaScript
  • $(function() {
  • $("#pieChartContainer").dxPieChart({
  • onLegendClick: function (e) {
  • var points = e.points;
  • // for a single-series PieChart
  • points[0].isVisible() ? points[0].hide() : points[0].show();
  •  
  • /* for a multi-series PieChart
  • points.forEach(function (point) {
  • point.isVisible() ? point.hide() : point.show();
  • });
  • */
  • }
  • });
  • });
