Chartjs-Data representation using charts

You can use chart.js with angular by injecting it.
If you want to change the type just set the type on the HTML

DEMO

angular.module("app", ["chart.js"])
  .controller("BarCtrl", function($scope) {
    $scope.commonEstimationStats = {
      rates: [{
        "direction": {
          "id": 13,
          "month": "2016",
          "type": 1
        },
        "points": 5
      }, {
        "direction": {
          "id": 14,
          "month": "2017",
          "type": 1
        },
        "points": 3
      }]
    };
    $scope.labels = [];
    $scope.data = [];
    angular.forEach($scope.commonEstimationStats.rates, function(key, value) {
      $scope.labels.push(key.direction.month);
      $scope.data.push(key.points);
    })
    $scope.datasetOverride = [{
      fill: true,
      backgroundColor: [
        "#66ff33",
        "#36A2EB",
        "#FFCE56"
      ]
    }, {
      fill: true,
      backgroundColor: [
        "#ffff00",
        "#46BFBD",
        "#FDB45C"
      ]
    }];
  });
