我想更改所选的每个城市或子城市的图表
我使用AngularJS开发了一个简单的应用程序，我想基于这个网站添加一个简单的图表Js Charts
这是我的 data.json：
[
{
"name": "city A",
"elements": [
{
"id": "c01",
"name": "name1",
"price": "15",
"qte": "10"

}
],

"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",

"price": "8",
"qte": "1"
},
{

"qte": "15"
},
{

}
]
}
]
},
{
"name": "city B",
"elements": [

},
{

"price": "18",
"qte": "17"
},
{
"id": "ccc03",
"name": "name333",
"price": "10",
"qte": "5"
}
]
}
]
我在这里打电话给我。
angular.module('app', [])
.controller('MainController', ['$scope', '$http', function($scope, $http) {

$scope.data = $scope.selectedCity.elements;
});
$scope.myJson = {

"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;
}
}
}]);
index.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>

<td>{{ item3.price }}</td>
</tr>
</table>
<zingchart id = "myChart" zc-json = "myJson" zc-height = 500 zc-width = 600 ></zingchart>
</body>
结果：
我想从属性name元素的城市
我想更改所选城市或子城市的图表。例如，如果我选择子集是sub A1，我需要获得如下图表：

但仍无效，无法加载图表
我有一个错误：

好吧，如果我理解你，那么你需要以下内容：
angular.module("myApp",['zingchart-angularjs'])
.controller('MainController', ['$scope', '$http', function($scope, $http) {
$scope.chartBase = {
"type": "line",
"plotarea": {
"adjust-layout": true /* For automatic margin adjustment. */
},
"scale-x": {
"label": {
"text": "Above is an example of a category scale" /* Add a scale title with a label object. */
},
"labels": ["name1", "name2", "name3"] /* Add your scale labels with a labels array. */
},
"series": [{
"values": [15, 18, 11] //here the prices of city selected
},{
"values": [10, 11, 14] //here the qte of city selected
}]
};
$scope.chartData = angular.copy($scope.chartBase);
$http.get('data.json')
.then(function(response) {
$scope.cities = response.data; // save the request data
$scope.selectedCity = $scope.cities[0]; // select the first one
$scope.changeCity(); // update chart
}, function(error) { console.log(error); });
$scope.changeCity = function() {
if($scope.selectedSubCity || $scope.selectedCity){ // if something has been selected
$scope.data = ($scope.selectedSubCity || $scope.selectedCity).elements; // update elements field
// initialize the array to be displayed in chart
var labels = [];
var price = {
"values": []
};
var qte = {
"values": []
};
// fill the arrays to be displayed from the selected city (sub city)
angular.forEach($scope.data, function(item, index) {
labels.push(item.name);
price.values.push(item.price);
qte.values.push(item.qte);
});
// put selected values to the field that is used to render the chart
$scope.chartData["scale-x"].labels = labels;
$scope.chartData.series = [ price, qte ];
}
}
}]);
我修改了一下你的控制器（和html页面）。以下是一个示例 - plunker。
困难（我可以看到）存在于您的data.json文件中。它有一个奇怪的结构。它结合了图表参数和数据本身。 （在我的例子中，我从中移除了图表参数并在控制器内硬编码。但这不是必需的。）
希望它会有所帮助。

ZingChart希望你在数组或数组数组中给它赋值，如果你想让它在图表中绘制多行。您的数据正在正确加载，因此您所要做的就是将所需的值推送到各自的数组中，并将该数组数组传递给图表。
我在您的选择框中添加了ng-change="extractSubsities(selectedCity)"，以便每当您更改选择时它都会更新图表。
然后在extractSubsities函数中添加一个简单的forEach，从当前选定的数据中生成数组，这样就可以得到我认为您正在寻找的内容。
$scope.extractSubsities = function(itemSelected) {
if(itemSelected && itemSelected.elements){
$scope.data = itemSelected.elements;
$scope.myData = itemSelected.elements
console.log(itemSelected.elements)
var price = []
var qte = []
itemSelected.elements.forEach(function(v) {
price.push(v.price)
qte.push(v.qte)
})
$scope.myData = [price, qte]
}
}
zingchart指令应如下所示：
<zingchart id = "myChart" zc-values = "myData" zc-height = 500 zc-width = 600 ></zingchart>
