How to pass json data to highcharts series?
提问by Pradip Shenolkar
I have following json array which is generated at runtime. Hence the number of name/data pairs varies.
我有以下在运行时生成的 json 数组。因此，名称/数据对的数量各不相同。
`var sales = { "SalesData" : [
{ "name" : "AllProducts|Canada", "data" :[44936.0,50752.0] },
{ "name" : "AllProducts|Mexico", "data" : [200679.0,226838.0] },
{ "name" : "AllProducts|USA", "data" : [288993.0,289126.0] }
]} `
I want to pass this data to series in highcharts.
我想将此数据传递给 highcharts 中的系列。
This is how I am doing it currently.
这就是我目前的做法。
series: [
{name:sales.SalesData[0].name,data:sales.SalesData[0].data},
{name:sales.SalesData[1].name,data:sales.SalesData[1].data},
{name:sales.SalesData[2].name,data:sales.SalesData[2].data}
]
But if the number of elements in array are changed then this won't work.How do I solve this problem ? Demo code will help me.
但是如果数组中的元素数量发生变化，那么这将不起作用。我该如何解决这个问题？演示代码将帮助我。
I have refereed following questions but I was not able to solve the problem.
我已经参考了以下问题，但我无法解决问题。

I solved the problem
我解决了这个问题
Changed json array as follows:
更改 json 数组如下：
var sales = [
{ "name" : "AllProducts123|Canada", "data" :[44936.0,50752.0] },
{ "name" : "AllProducts|Mexico", "data" : [200679.0,226838.0] },
{ "name" : "AllProducts|USA", "data" : [288993.0,289126.0] }
]
Now pass it directly to series in highcharts.
现在将它直接传递给 highcharts 中的系列。
series:sales
Done !!!!!
完毕 ！！！！！

Instead of constructing the seriesarray manually you could loop through the salesvariable data and construct the array. So what ever the number of elements in the sales.SalesDataarray, all items will be there in the seriesarray
series您可以遍历sales变量数据并构建数组，而不是手动构建数组。因此，无论sales.SalesData数组中有多少元素，所有项目都将在series数组中
var series = [],
salesData= sales.SalesData;
for (var i=0 i< salesData.length; i++) {
series.push({"name" : key, "data" : sales[key]})
}
This constructed seriesarray is part of the object which you must pass as argument to highchartsmethod.
这个构造的series数组是您必须作为参数传递给highcharts方法的对象的一部分。
var chartdata = {
chart: {type: 'column'},
title: {text: 'Sales Data'},
xAxis: {
categories: ['Category 1','Category 2']
},
yAxis: {
min: 0,
title: {text: 'Sales'}
},
series : []
}
chartdata.series = series;
$('#chart').highcharts(chartdata);
where #chart is the container where you want to display the chart.
其中#chart 是您要显示图表的容器。
you can also refer to the fiddles which are available in their demo pagesfor each type of chart to know more on how to display a particular type of chart.
您还可以参考每种类型图表的演示页面中提供的小提琴，以了解有关如何显示特定类型图表的更多信息。
