使用rootScope在控制器之间共享日期

Question

我有两个控制器，我想分享他们的数据。 第一个控制器是＆＃39; MyController＆＃39;，它在图表上显示数据。 第二个控制器称为服务，并带来了一系列公司。 我想用rootScope分享数组的大小并将其显示在图表上。 非常感谢帮助

(function() {

    var module = angular.module("couponSystem");
    /**
     * MyController, Which is responsible for drawing the chart inside the admin page
     */
    module.controller('MyController', function($scope,$rootScope) {
        $rootScope.companies = [];
        var self = this;

        // chart data source
        $scope.dataSource = {
                "chart": {
                    "caption": "USER CHART",
                    "subCaption": "properties",
                    "dataFormat" :"json",
                    "xAxisName": "USERS",
                    "yAxisName": "NUMBER",
                    "paletteColors": "#0075c2",
                    "bgColor": "#ffffff",
                    "borderAlpha": "20",
                    "plotBorderAlpha": "10",
                    "placevaluesInside": "1",
                    "rotatevalues": "1",
                    "valueFontColor": "#ffffff",
                    "showXAxisLine": "1",
                    "xAxisLineColor": "#999999",
                    "divlineColor": "#999999",
                    "divLineDashed": "1",
                    "showAlternateHGridColor": "0",
                    "subcaptionFontBold": "0",
                    "subcaptionFontSize": "14"
                },
            "data" : [ {
                "label" : "No' of companies",
                "value" : $rootScope.companies.length
            },
            {
                "label" : "No' of customers",
                "value" : "11"
            },
            {
                "label" : "No' of coupons",
                "value" : "18"
            },
            // more chart data
            ]
        };
    });
})();
 second controller :




(function() {

    var module = angular.module("couponSystem");

    module.controller("GetAllCompaniesCtrl", GetAllCompaniesCtrlCtor);
    /**
     * get all Companies controller CTRL with ngConfirm - A controller that
     * allows the get all of Companies from the database, under administrator
     * permissions
     */
    function GetAllCompaniesCtrlCtor(mainAdminServiceHTTP, $ngConfirm, $state,
            $scope,$rootScope) {
        this.companies = [];
        $rootScope.companies = [];
        var self = this;
        /**
         * Get all companies function. The method receives the answer from the
         * service into the Promise, using the mainAdminService. If the

        var promise = mainAdminServiceHTTP.getAllCompanies();
        promise.then(function(resp) {

        }, function(err) {
