使用下面的代码生成一个时间线图时，使用AngularJS，iam面临一个问题。

基本上，iam无法找到导入时间线包的正确方法。就像导入代码图表包下面的导入一样，我如何导入时间线.

google.load('visualization', '1', {packages: ['corechart']});

我试着用

<script type="text/javascript"  src="https://www.google.com/jsapi?autoload={'modules':[{'name':'visualization','version':'1','packages':['timeline']}]}"></script>

别说了，没用的。

控制器

"use strict";

/*We need to manually start angular as we need to
wait for the google charting libs to be ready*/  
google.setOnLoadCallback(function () {  
    angular.bootstrap(document.body, ['my-app']);
});
google.load('visualization', '1', {packages: ['corechart']});


var myApp = myApp || angular.module("my-app",["google-chart"]);

myApp.controller("IndexCtrl",function($scope){  
    $scope.data1 = {};
    $scope.data1.dataTable = new google.visualization.DataTable();
    $scope.data1.dataTable.addColumn("string","Name")
    $scope.data1.dataTable.addColumn("number","Qty")
    $scope.data1.dataTable.addRow(["Test",1]);
    $scope.data1.dataTable.addRow(["Test2",2]);
    $scope.data1.dataTable.addRow(["Test3",3]);
    $scope.data1.title="My Pie"

    $scope.data2 = {};
    $scope.data2.dataTable = new google.visualization.DataTable();
    $scope.data2.dataTable.addColumn("string","Name")
    $scope.data2.dataTable.addColumn("number","Qty")
    $scope.data2.dataTable.addRow(["Test",1]);
    $scope.data2.dataTable.addRow(["Test2",2]);
    $scope.data2.dataTable.addRow(["Test3",3]);


    $scope.data4 = {};
    $scope.data4.dataTable = new google.visualization.DataTable();
    $scope.data4.dataTable.addColumn({ type: 'string', id: 'President' })
    $scope.data4.dataTable.addColumn({ type: 'date', id: 'Start' })
    $scope.data4.dataTable.addColumn({ type: 'date', id: 'End' })
    $scope.data4.dataTable.addRows([[ 'Down',      new Date(1797, 2, 3,20.20),  new Date(1797, 2, 4,21.20) ],
          [ 'Jefferson',  new Date(1801, 2, 4,20.20),  new Date(1801, 2, 4,20.20) ]]);

    $scope.data3 = {};
    $scope.data3.dataTable = new google.visualization.DataTable();
    $scope.data3.dataTable.addColumn("string","Name")
    $scope.data3.dataTable.addColumn("number","Qty")
    $scope.data3.dataTable.addRow(["Test",1]);
    $scope.data3.dataTable.addRow(["Test2",2]);
    $scope.data3.dataTable.addRow(["Test3",3]);
});

很可能是因为google-chart指令的值设置为TimeLine，并且无法找到具有此键的对象，因此很可能会出现错误：

var googleChart = new google.visualization[$attr.googleChart]($elem[0]);

时间谷歌图的类名是google.visualization.Timeline

因此，解决方案是将TimeLine的值替换为Timeline

<div google-chart="Timeline" ng-model="data4" class="smallGraph"></div>
