Creating multiple CanvasJS charts inside <div> with ng-repeat

Question

I am trying to create multiple CanvasJS charts inside a div.

The div expects array of data from controller, loops through it(using ng-repeat) and displays the data in various controls.

Now when I try to put a CanvasJS Chart inside this div, the chart does not render and the error I see is 'chart with id is not found'

But the same chart works well just outside this div.

Sample code here: http://jsfiddle.net/DTheWebDev/mozfsxpc/7/

APP.JS

var m = {
  "India": "2",
  "Australia": "3"
};

function MyCtrl($scope) {
  $scope.items = m;
}
var dps = [{
  x: 1,
  y: 10
}]; //dataPoints. 

var chart = new CanvasJS.Chart("chartContainer", {
  title: {
    text: "Live Data"
  },
  axisX: {
    title: "Axis X Title"
  },
  axisY: {
    title: "Units"
  },
  data: [{
    type: "line",
    dataPoints: dps
  }]
});

chart.render();
var xVal = dps.length - 1;
var yVal = 15;
var updateInterval = 1000;

var updateChart = function() {
  yVal = yVal + Math.round(5 + Math.random() * (-5 - 5));
  dps.push({
    x: xVal,
    y: yVal
  });
  xVal--;
  chart.render();

};
setInterval(function() {
  updateChart()
}, updateInterval);

HTML:

<h3>Match Summary:</h3>

<div ng-app ng-controller="MyCtrl">
  <div ng-repeat="(country,goals) in items">
    <div id="chartContainer" style="height: 200px; width: 100%;"></div>
    <h2>{{country}}: {{goals}} </h2>
  </div>
</div>

Tried to search with similar problem, but no luck.

Thanks for your time and help in advance.

The flow of the program should be taken care of. It throws the error 'Chart with ID is not found' as chart is tried to being rendered on a div element which doesn't exist yet. Also, the ids of different div elements should be different. You can use code similar to this to append dynamic id.

<div ng-repeat="(country,goals) in items"> 
    <div id="chartContainer-{{country}}" style="height: 200px; width: 100%;"></div>
<h2>{{country}}: {{goals}} </h2>
</div>

Here is the working jsfiddle
