在HighCharts中使用JSON对象 [英] Using a JSON Object in HighCharts
本文介绍了在HighCharts中使用JSON对象的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我是HighCharts的新手,我想知道如何将本地JSON对象读入HighCharts中的堆积条形图。我相信我编写了系列和类别,但由于某种原因,getJson函数无法正常工作。
$ b Angular JS File
函数get_chart(){
return {
图:{
类型:'列'
} ,
title:{
text:'Twitter Data'
},
xAxis:{
categories:[]
},
plotOptions:{
系列:{
堆叠:'普通',
dataLabels:{
启用:true,
样式:{
textShadow :'0 0 3px black'
}
},点:{
events:{
click:function(){
alert('Category:'+ this .category +',value:'+ this.y);
}
}
}
}
},
系列:[]
},
$ .getJSON(js / data.json,function(json){
options.xAxis.categories = json [0] ['data'];
options.series [0] = json [1];
options.series [1] = json [2];
chart = new Highcharts.Chart(options);
});
}
var app = angular.module('charts',[]);
app.directive('highchart',[function(){
return {
restrict:'E',
template:'< div>< / div>',
替换为:true,
link:函数(范围,元素,attrs){
$ b $ scope。$ watch(attrs.chart,function(){
if(!attrs.chart)return;
var chart = scope。$ eval(attrs.chart);
angular.element(element ).highcharts(chart);
});
}
}
}]);
函数Ctrl($ scope){
$ scope.example_chart = get_chart();
JSON对象
[
{
name:Month,
data:[
Jan ,
Feb,
Mar,
Apr,
May,
Jun,
Jul,
Aug,
Sep,
Oct,
Nov,
Dec
]
},
[
{
name:Overhead,
data:[
21990,
22365,
21987,
22369,
22558,
22987,
23521,
23003,
22756,$ b 23112,
22987,
22897
$ b $ name b
$
24784,
25899,
25569,
25897,
25668,
24114,
23899,
24987,
25111,
25899,
2 3221
]
}
]
解决方案通过外部json文件调用查看Plunker演示
function get_chart(){
var options = {
chart:{
type:'column',
renderTo:'container'
},
title:{
text:'Twitter Data'
},
xAxis:{
categories:[ ]
},
plotOptions:{
series:{
stacking:'normal',
dataLabels:{
enabled:true,
style:{
textShadow:'0 0 3px black'
}
},point:{
events:{
click:function(){
alert('Category:'+ this.category +',value:'+ this.y );
}
}
}
}
},
系列:[]
};
$ .getJSON(results.json,function(json){
options.xAxis.categories = json [0] ['data'];
options.series [0] = json [1];
options.series [1] = json [2];
chart = new Highcharts.Chart(options);
});
}
get_chart(); //在你想要的控制器中调用这个get_chart函数,我在这里调用它。
I am new to HighCharts and I am trying to figure out how to read a local JSON object into my stacked bar graph in HighCharts. I believe I wrote the series and categories but for some reason the getJson Function is not working.
Angular JS File
function get_chart() {
return {
chart: {
type: 'column'
},
title: {
text: 'Twitter Data'
},
xAxis: {
categories: []
},
plotOptions: {
series: {
stacking: 'normal',
dataLabels: {
enabled: true,
style: {
textShadow: '0 0 3px black'
}
}, point: {
events: {
click: function () {
alert('Category: ' + this.category + ', value: ' + this.y);
}
}
}
}
},
series: []
},
$.getJSON("js/data.json", function(json) {
options.xAxis.categories = json[0]['data'];
options.series[0] = json[1];
options.series[1] = json[2];
chart = new Highcharts.Chart(options);
});
}
var app = angular.module('charts', []);
app.directive('highchart', [function () {
return {
restrict: 'E',
template: '<div></div>',
replace: true,
link: function (scope, element, attrs) {
scope.$watch(attrs.chart, function () {
if (!attrs.chart) return;
var chart = scope.$eval(attrs.chart);
angular.element(element).highcharts(chart);
});
}
}
}]);
function Ctrl($scope) {
$scope.example_chart = get_chart();
}
JSON Object
[
{
"name": "Month",
"data": [
"Jan",
"Feb",
"Mar",
"Apr",
"May",
"Jun",
"Jul",
"Aug",
"Sep",
"Oct",
"Nov",
"Dec"
]
},
[
{
"name": "Overhead",
"data": [
21990,
22365,
21987,
22369,
22558,
22987,
23521,
23003,
22756,
23112,
22987,
22897
]
}
],
{
"name": "Revenue",
"data": [
23987,
24784,
25899,
25569,
25897,
25668,

23899,

}

解决方案
Calling via external json file See Plunker demo
function get_chart() {
var options = {
chart: {
type: 'column',
renderTo:'container'
},
title: {
text: 'Twitter Data'
},
xAxis: {
categories: []
},
plotOptions: {
series: {
stacking: 'normal',
dataLabels: {
enabled: true,
style: {
textShadow: '0 0 3px black'
}
}, point: {
events: {
click: function () {
alert('Category: ' + this.category + ', value: ' + this.y);
}
}
}
}
},
series: []
};
$.getJSON("results.json", function(json) {
options.xAxis.categories = json[0]['data'];
options.series[0] = json[1];
options.series[1] = json[2];
chart = new Highcharts.Chart(options);
});
}
get_chart(); //call this get_chart function in your controller where you want, I called it here.
