// Simulate async data update
$timeout(function () {
$scope.data = [
[28, 48, 40, 19, 86, 27, 90],
[65, 59, 80, 81, 56, 55, 40]
];
}, 3000);
}]);

Answer

I put the corrections I mentioned in the comments, ng-app and ng-directives are missing.

script.js

angular.module("app", ["chart.js"]) // here i couldn't understand about chart.js fil
  // Optional configuration
  .config(['ChartJsProvider', function (ChartJsProvider) {
    // Configure all charts
    ChartJsProvider.setOptions({
      colours: ['#FF5252', '#FF8A80'],
      responsive: false
    });
    // Configure all line charts
    ChartJsProvider.setOptions('Line', {
      datasetFill: false
    });
  }])
  .controller("LineCtrl", ['$scope', '$timeout', function ($scope, $timeout) {

  $scope.labels = ["January", "February", "March", "April", "May", "June", "July"];
  $scope.series = ['Series A', 'Series B'];
  $scope.data = [
    [65, 59, 80, 81, 56, 55, 40],
    [28, 48, 40, 19, 86, 27, 90]
  ];
  $scope.onClick = function (points, evt) {
    console.log(points, evt);
  };

  // Simulate async data update
  $timeout(function () {
    $scope.data = [
      [28, 48, 40, 19, 86, 27, 90],
      [65, 59, 80, 81, 56, 55, 40]
    ];
  }, 3000);
}]);

I made a jsbin for it.
