Ways to retrieve the related file in Angular service files?

I am looking to retrieve an array from another service file (chart-serv.js) in my return-serv.js service file using AngularJS. How can I reference the dependent file enclosed within double braces [ ], in line 1?

return-serv.js

 var app = angular.module('starter.return-serv', ['starter.chart-serv'])

 app.factory("ReturnData", function() {
     return {
         allData: function() {
             var data = starter.chart - serv.chartPricesUpTo6Hours;
             return data
         }
     }
 });

chart-serv.js

 var app = angular.module('starter.chart-serv', [])

 var chartPricesUpTo6Hours = {
     "10": {
         "1": 95,
         "2": 125,
         "3": 155,
         "4": 185,
         "5": 215,
         "6": 245
     },
     "20": {
         "1": 105,
         "2": 135,
         "3": 165,
         "4": 195,
         "5": 225,
         "6": 255
     }
 };

I am unsure about how to access the other file within the data variable of the allData function. What should be called to access it?

To send data from chartserv.js to returnserv.js, you can create a service in chartserv.js and inject it into a factory.

chartserv.js:

var app = angular.module('chartserv', []);

app.service('DataTransferService', function(){

    var chartPricesUpTo12Hours = {
     "10": {
         "1": 95,
         "2": 125,
         "3": 155,
         "4": 185,
         "5": 215,
         "6": 245
     },
     "20": {
         "1": 105,
         "2": 135,
         "3": 165,
         "4": 195,
         "5": 225,
         "6": 255
     }
    };

    return {chartPricesUpTo12Hours: chartPricesUpTo12Hours};

});

returnserv.js:

var app = angular.module('returnserv', []);

app.factory("RetrieveDataService", function(DataTransferService) {
    return {
        getAllData: function() {

            var dataFromService = DataTransferService.chartPricesUpTo12Hours;
            return dataFromService;

        }
    }
});

To include a JavaScript file in your project, start by adding it to your index.html like this:

<script src="path/to/file/starter.chart.js">

In the starter.chart.js file, define your module or attach it to another module like so:

angular.module('start.chart')

Or if it's a controller: angular.module('module to attach to').controller('controller name')

Below is an example code snippet from an app I created for reference:

app.module.js:

angular.module('ffApp', ['ionic', 'controllers', 'services', 'angulartics', 'angulartics.google.analytics', 'ngCordova', 'pdf', 'ngSanitize', 'ngImgCrop', 'chart.js']);

app.controller.js:

angular.module('controllers', ['ionic', 'ngCordova', 'services', 'pdf', 'ngSanitize', 'ngImgCrop', 'chart.js']);

home.controller.js:

angular.module('controllers').controller('home.controller', function ($scope, ffService, $state, $http, $ionicHistory, $ionicSideMenuDelegate, $rootScope, $cordovaCamera, $ionicPlatform, $ionicLoading)

When loading my app.modules, they rely on the controllers module which fetches all attached controllers even if they are in separate files. Don't forget to load them in your index.html as well.
