angular-chartjs折线图TypeError:t.merge不是函数

Question

我正在尝试使用折线图示例@ http://jtblin.github.io/angular-chart.js/.我收到以下错误.任何人都可以提供一些指示吗？

控制台错误

这是我的代码.我已经尝试将html移出ui-view以查看角度是否有任何问题但是在布局页面上也不起作用.几乎从网站上复制粘贴示例代码.

angular.module('app').controller(controllerId, [
        '$scope', function ($scope) {
          //Line Chart
            $scope.lineLabels = ["January", "February", "March", "April", "May", "June", "July"];
            $scope.lineSeries = ['Series A', 'Series B'];
            $scope.lineData = [
              [65, 59, 80, 81, 56, 55, 40],
              [28, 48, 40, 19, 86, 27, 90]
            ];
           
            $scope.lineDatasetOverride = [{ yAxisID: 'y-axis-1' }, { yAxisID: 'y-axis-2' }];
            $scope.lineOptions = {
                scales: {
                    yAxes: [
                      {
                          id: 'y-axis-1',
                          type: 'linear',
                          display: true,
                          position: 'left'
                      },
                      {
                          id: 'y-axis-2',
                          type: 'linear',
                          display: true,
                          position: 'right'
                      }
                    ]
                }
            };
          }
]);

检查你的 Angular 版本...我认为你使用的是 1.2.X 版本，它还没有合并功能，而 angular-chart.js 使用此功能。

您可以做的是使用此代码，将其放在角度加载之后、图表加载之前......

if (!angular.merge) {
  angular.merge = (function mergePollyfill() {
    function setHashKey(obj, h) {
      if (h) {
        obj.$$hashKey = h;
      } else {
        delete obj.$$hashKey;
      }
    }

    function baseExtend(dst, objs, deep) {
      var h = dst.$$hashKey;

      for (var i = 0, ii = objs.length; i < ii; ++i) {
        var obj = objs[i];
        if (!angular.isObject(obj) && !angular.isFunction(obj)) continue;
        var keys = Object.keys(obj);
        for (var j = 0, jj = keys.length; j < jj; j++) {
          var key = keys[j];
          var src = obj[key];

          if (deep && angular.isObject(src)) {
            if (angular.isDate(src)) {
              dst[key] = new Date(src.valueOf());
            } else {
              if (!angular.isObject(dst[key])) dst[key] = angular.isArray(src) ? [] : {};
              baseExtend(dst[key], [src], true);
            }
          } else {
            dst[key] = src;
          }
        }
      }

      setHashKey(dst, h);
      return dst;
    }

    return function merge(dst) {
      return baseExtend(dst, [].slice.call(arguments, 1), true);
    }
  })();
}
