我有一个 json 对象，我正在尝试将其添加到我的 highcharts 选项中。
我能够通过 API 接收该对象，并将其传递给我的 highcharts 函数，但我无法将我的数据添加到它周围的静态数据中。
var datas;
datas = getData();
//getdata();
alert('2datass'+datas);
console.log(datas);
createChart(datas);
function createChart(data){
alert('createChart'+data); // works - outputs createChart[object Object][object Object][object Object][object Object][object Object]
var dynamicData;
for(var i =0;i <= data.length-1;i++)
{
var item = data[i];
dynamicData = dynamicData + {
type: 'column',
name: item.name,
data: [item.difference]
};
}
alert('dynamic' +dynamicData); // works, but says undefined before - outputs dynamic undefined[object Object][object Object][object Object][object Object][object Object]
var series = [data /*This is where my data should sit*/,{
type: 'column',
name: 'Jane',
data: [300, 30]
}, {
type: 'column',
name: 'John',
data: [-200, 50]
}, {
type: 'column',
name: 'Joe',
data: [444, -25]
}, {
type: 'column',
name: 'Jobe',
data: [444, -25]
}, {
type: 'column',
name: 'Jooe',
data: [444, -25]
},{
type: 'column',
name: 'Jane',
data: [300, 30]
}
, {
type: 'pie',
name: 'Total consumption',
data: [{
name: 'Jane',
y: 13
//color: '#4572A7' // Jane's color
}, {
name: 'John',
y: 23
//color: '#AA4643' // John's color
}, {
name: 'Joe',
y: 19
//color: '#89A54E' // Joe's color
}],
center: [30, 80],
size: 100,
showInLegend: false,
dataLabels: {
enabled: false
}
}];
var options = {
chart: {
renderTo: 'container'
},
title: {
text: 'Account Managers Leaderboard'
},
xAxis: {
categories: ['Month on Month', 'Day on Day']
},
tooltip: {
formatter: function() {
var s;
if (this.point.name) { // the pie chart
s = ''+
this.point.name +': '+ this.y +' sales';
} else {
s = ''+
this.x +': '+ this.y;
}
return s;
}
},
labels: {
items: [{
html: 'Total proportion of sales <br />this month',
style: {
left: '40px',
top: '-5px',
color: 'black'
}
}]
},
series: series
};
$(document).ready(function() {
var chart;
chart = new Highcharts.Chart(options);
});
}
function getData(){
//alert('ajax');
var receivedData; // store your value here
$.ajax({
type: "GET",
dataType: "json",
url: "API URL",
async: false,
success: function(data){
alert('data'+data); //works
receivedData = data;
}
});
return receivedData;
};
我的解决方案似乎是错误的，因为没有添加动态数据。任何帮助将不胜感激。
更新的代码:
var dynamicData = {
type: 'column',
name: 'FIRST',
data: [300, 30]
};
//Without the following loop, my chart will display the above entry "FIRST"
//With the loop, the chart omits everything in dynamicData
for(var i =0;i <= data.length-1;i++)
{
var item = data[i];
dynamicData = dynamicData + {
type: 'column',
name: item.name,
data: [item.difference]
};
}
alert('dynamic' +dynamicData); // works, but says undefined before - outputs dynamic undefined[object Object][object Object][object Object][object Object][object Object]
//dynamicData should be 'FIRST' and then 5 other returned rows
var series = [dynamicData, {
type: 'column',
name: 'John',
data: [-200, 50]
}, {
type: 'column',
name: 'Joe',
data: [444, -25]
}, {
type: 'column',
name: 'Jobe',
data: [444, -25]
}, {
type: 'column',
name: 'Jooe',
data: [444, -25]
},{
type: 'column',
name: 'Jane',
data: [300, 30]
}
, {
type: 'pie',
name: 'Total consumption',
data: [{
name: 'Jane',
y: 13
//color: '#4572A7' // Jane's color
}, {
name: 'John',
y: 23
//color: '#AA4643' // John's color
}, {
name: 'Joe',
y: 19
//color: '#89A54E' // Joe's color
}],
center: [30, 80],
size: 100,
showInLegend: false,
dataLabels: {
enabled: false
}
}];
使用 .push 修改代码:
// series has been moved straight into the options variable
var options = {
chart: {
renderTo: 'container'
},
title: {
text: 'Account Managers Leaderboard'
},
xAxis: {
categories: ['Month on Month', 'Day on Day']
},
tooltip: {
formatter: function() {
var s;
if (this.point.name) { // the pie chart
s = ''+
this.point.name +': '+ this.y +' sales';
} else {
s = ''+
this.x +': '+ this.y;
}
return s;
}
},
labels: {
items: [{
html: 'Total proportion of sales <br />this month',
style: {
left: '40px',
top: '-5px',
color: 'black'
}
}]
},
series: [{
type: 'pie',
name: 'Total consumption',
data: [{
name: 'Jane',
y: 13
//color: '#4572A7' // Jane's color
}, {
name: 'John',
y: 23
//color: '#AA4643' // John's color
}, {
name: 'Joe',
y: 19
//color: '#89A54E' // Joe's color
}],
center: [30, 80],
size: 100,
showInLegend: false,
dataLabels: {
enabled: false
}
}]
};
//I can now push data straight to seriese (although item.difference doesn't
// work .. perhaps because it's an array)
for(var i =0;i <= data.length-1;i++)
{
var item = data[i];
options.series.push({
"type": "column",
"name": item.name,
"data": item.data
});
alert('datavalue' +item.data);
}
$(document).ready(function() {
var chart;
chart = new Highcharts.Chart(options);
});
回答!
这似乎可以解决问题。感谢 Speransky Danil 与我一起奋斗 - 非常感谢。
var datas;
datas = getData();
createChart(datas);
function createChart(data){
var options = {
chart: {
renderTo: 'container'
},
title: {
text: 'Account Managers Leaderboard'
},
xAxis: {
categories: ['Month on Month', 'Day on Day']
},
tooltip: {
formatter: function() {
var s;
if (this.point.name) { // the pie chart
s = ''+
this.point.name +': '+ this.y +' sales';
} else {
s = ''+
this.x +': '+ this.y;
}
return s;
}
},
labels: {
items: [{

}
}]
};
for(var i =0;i <= data.length-1;i++)
{
var item = data[i];
options.series.push({
"type": "column",
"name": item.name,
"data": [item.data]
});
}
$(document).ready(function() {
var chart;
chart = new Highcharts.Chart(options);
});
}
function getData(){
//alert('ajax');
var receivedData; // store your value here
$.ajax({
type: "GET",

success: function(data){
alert('data'+data); //works
receivedData = data;

});
return receivedData;
};
最佳答案
问题出在循环中，其中包含:
dynamicData = dynamicData + {
type: 'column',
name: item.name,
data: [item.difference]
};
第一次dynamicData是未定义。当我们对 undefined 和 Object 求和时，我们将它们都转换为 string 并将其连接起来，这样你就得到字符串 'undefined'[object Object]'，然后 'undefined[object Object][object Object]' 等等(转换为 string 对象为 ' [对象对象]')。
