javascript - Angular 图饼图数据点击事件

Question

Angular JS 图表很棒，但我需要在我创建的饼图中实现点击事件..这是编码..

这是 JavaScript 编码...

  $scope.pied = [{
          value: 4,
          color: "#FF5A5E",
          highlight: "#FF5A5E",
          label: "Prospective"
        }, {
          value: 0,
          color: "#46BFBD",
          highlight: "#46BFBD",
          label: "Pending"
        }, {
          value: 0,
          color: "#FDB45C",
          highlight: "#FDB45C",
          label: "CallBacks"
        }, {
          value: 4,
          color: "#e6e6fa",
          highlight: "#e6e6fa",
          label: "FollowUp"
        }, {
          value: 1,
          color: "#cc5229",
          highlight: "#cc5229",
          label: "Not Interested"
        }, {
          value: 0,
          color: "#556b2f",
          highlight: "#556b2f",
          label: "Close"
        }]

        var pieOptions = {
          //Boolean - Whether we should show a stroke on each segment
          segmentShowStroke: true,

          //String - The colour of each segment stroke
          segmentStrokeColor: "#fff",

          //Number - The width of each segment stroke
          segmentStrokeWidth: 2,

          //Boolean - Whether we should animate the chart
          animation: true,

          //Number - Amount of animation steps
          animationSteps: 100,

          //String - Animation easing effect
          animationEasing: "easeOutBounce",

          //Boolean - Whether we animate the rotation of the Pie
          animateRotate: true,

          //Boolean - Whether we animate scaling the Pie from the centre
          animateScale: false,

          //Function - Will fire on animation completion.
          onAnimationComplete: null

        }
        var ctx = document.getElementById("pieChart").getContext("2d");
        var myPieChart = new Chart(ctx).Pie($scope.pied, pieOptions);
        ctx.onclick = function(evt){
        var activePoints = myPieChart.getPointsAtEvent(evt);
        console.log("active: "+activePoints);
        // => activePoints is an array of points on the canvas that are at the same position as the click event.
    };
        document.getElementById('js-legend').innerHTML = myPieChart.generateLegend();

This is the HTML Coding..
 <canvas id="pieChart" width="440" height="200" ></canvas>
   <div id="js-legend" class="chart-legend"></div>

这是上面程序的图像..我已经编写了代码，当我单击 The FollowUP 时，它必须与之相关的数据..但是单击事件不起作用..？

请查看上面的代码和图片，并指导我获得我期望的确切输出。预先感谢大家...

我使用了 angular-chart.js 来代替这个 chart.js Angular JS 文档是 here 。 Angular Chart 比 Chart.js 稍微简单一点..

感谢大家的支持..:)
