我用 AngularJS 开发了一个简单的应用程序，我想添加一个基于这个网站的简单图表Js Charts
这是我的data.json：
[
{
"name": "city A",
"elements": [
{
"id": "c01",
"name": "name1",
"price": "15",
"qte": "10"
},
{
"id": "c02",
"name": "name2",
"price": "18",
"qte": "11"
},
{
"id": "c03",
"name": "name3",
"price": "11",
"qte": "14"
}
],
"subsities": [
{
"name": "sub A1",
"elements": [
{
"id": "sub01",
"name": "nameSub1",
"price": "1",
"qte": "14"
},
{
"id": "sub02",
"name": "nameSub2",
"price": "8",
"qte": "13"
},
{
"id": "sub03",
"name": "nameSub3",
"price": "1",
"qte": "14"
}
]
},
{
"name": "sub A2",
"elements": [
{
"id": "ssub01",
"name": "nameSsub1",
"price": "1",
"qte": "7"
},
{
"id": "ssub02",
"name": "nameSsub2",
"price": "8",
"qte": "1"
},
{
"id": "ssub03",
"name": "nameSsub3",
"price": "4",
"qte": "19"
}
]
},
{
"name": "sub A3",
"elements": [
{
"id": "sssub01",
"name": "nameSssub1",
"price": "1",
"qte": "11"
},
{
"id": "sssub02",
"name": "nameSssub2",
"price": "2",
"qte": "15"
},
{
"id": "sssub03",
"name": "nameSssub3",
"price": "1",
"qte": "15"
}
]
}
]
},
{
"name": "city B",
"elements": [
{
"id": "cc01",
"name": "name11",
"price": "10",
"qte": "11"
},
{
"id": "cc02",
"name": "name22",
"price": "14",
"qte": "19"
},
{
"id": "cc03",
"name": "name33",
"price": "11",
"qte": "18"
}
]
},
{
"name": "city C",
"elements": [
{
"id": "ccc01",
"name": "name111",
"price": "19",
"qte": "12"
},
{
"id": "ccc02",
"name": "name222",
"price": "18",
"qte": "17"
},
{
"id": "ccc03",
"name": "name333",
"price": "10",
"qte": "5"
}
]
}
]
我在这里称我的数据。
angular.module('app', [])
.controller('MainController', ['$scope', '$http', function($scope, $http) {
$http.get('js/controllers/data.json').then(function(response) {
$scope.cities = response.data;
$scope.selectedCity = $scope.cities[0];
$scope.data = $scope.selectedCity.elements;
});
$scope.myJson = {
"type": "line",
"plotarea": {
"adjust-layout":true /* For automatic margin adjustment. */
},
"scale-x": {
"label": { /* Add a scale title with a label object. */
"text":"Above is an example of a category scale",
},
/* Add your scale labels with a labels array. */
"labels":["name1","name2","name3"]
},
"series": [
{"values":[15,18,11]},//here the prices of city selected
{"values":[10,11,14]}//here the qte of city selected
]
};
$scope.extractSubsities = function(itemSelected) {
if (itemSelected && itemSelected.elements) {
$scope.data = itemSelected.elements;
}
}
}]);
索引.html：
<body ng-controller="MainCtrl">
<select ng-model="selectedCity" ng-change="extractSubsities(selectedCity)" ng-options="item as item.name for item in cities track by item.name" ng-init="selectedCity = cities[0];extractSubsities(selectedCity)">
</select>
<select ng-show="selectedCity.subsities" ng-model="selectedSubCity" ng-change="extractSubsities(selectedSubCity)" ng-options="item2 as item2.name for item2 in selectedCity.subsities track by item2.name">
<option style="" value=""></option>
</select>
<table>
<tr ng-repeat="item3 in data track by item3.id">
<td>{{ item3.id }}</td>
<td>{{ item3.name }}</td>
<td>{{ item3.price }}</td>
</tr>
</table>
<zingchart id = "myChart" zc-json = "myJson" zc-height = 500 zc-width = 600 ></zingchart>
</body>
的结果：
我想从属性name元素的城市中提取
我想更改所选的每个城市或子城市的图表。例如，如果我选择子城市，sub A1我需要获得如下图表：
请帮我 ！
更新：
我试图只使用一个数据源文件
[{
"type": "line",
"plotarea": {
"adjust-layout": true
},

"label": {
"text": "échelle essence gazoile"
},

我在这里调用了我的数据：
angular.module('app', []).controller('MainController', ['$scope', '$http', function($scope, $http) {
$http.get('js/controllers/data.json').then(function(response) {
$scope.cities = response.data;
$scope.myJson=response.data;
$scope.selectedCity = $scope.cities[0];
$scope.data = $scope.selectedCity.elements;
}, function(error) { console.log(error); });
$scope.name = 'World';
$scope.data;
$scope.extractSubsities = function(itemSelected) {
if(itemSelected && itemSelected.elements){
$scope.data = itemSelected.elements;
}
}
}]);
索引.html：
<body ng-controller="MainCtrl">
<select ng-model="selectedCity" ng-change="extractSubsities(selectedCity)" ng-options="item as item.name for item in cities track by item.name" ng-init="selectedCity = cities[0];extractSubsities(selectedCity)">
</select>
<select ng-show="selectedCity.subsities" ng-model="selectedSubCity" ng-change="extractSubsities(selectedSubCity)" ng-options="item2 as item2.name for item2 in selectedCity.subsities track by item2.name">
<option style="" value=""></option>
</select>
<table>
<tr ng-repeat="item3 in data track by item3.id">
<td>{{ item3.id }}</td>
<td>{{ item3.name }}</td>
<td>{{ item3.price }}</td>
</tr>
</table>
</div>
<zingchart id = "myChart" zc-json = "myJson" zc-height = 500 zc-width = 600 ></zingchart>
</body>
但仍然不起作用它无法加载图表
我有一个错误：
类型错误：无法读取未定义的属性“类型”
更新 2：
我在 plunkr 中进行了设置：plnkr。
