如何使用AngularJS动态更新Ignite UI igDataChart

<script src="path/to/angular.js"></script>
<script src="path/to/infragistics.core.js"></script>
<script src="path/to/infragistics.lob.js"></script>
<link rel="stylesheet" href="path/to/infragistics.css">

var app = angular.module('myApp', ['igniteui-directives']);

<div ng-app="myApp" ng-controller="myCtrl">
  <ig-data-chart id="chart" ig-theme="light" ig-data-source="data"></ig-data-chart>
</div>

app.controller('myCtrl', function($scope) {
  $scope.data = [
    { "year": "2015", "value": 100 },
    { "year": "2016", "value": 200 },
    { "year": "2017", "value": 150 },
    { "year": "2018", "value": 300 },
    { "year": "2019", "value": 250 }
  ];

  $scope.updateData = function() {
    // 更新数据的逻辑
    // 可以通过修改$scope.data来更新图表的数据
  };
});

<button ng-click="updateData()">更新数据</button>
