How to pass json data to highcharts series?

Question

I have following json array which is generated at runtime. Hence the number of name/data pairs varies.

`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.

This is how I am doing it currently.

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.

I have refereed following questions but I was not able to solve the problem.

Highcharts series data array

Answer 1

I solved the problem

Changed json array as follows:

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.

 series:sales

Done !!!!!

Answer 2

Instead of constructing the series array manually you could loop through the sales variable data and construct the array. So what ever the number of elements in the sales.SalesData array, all items will be there in the series array

var series = [],
    salesData= sales.SalesData;

for (var i=0 i< salesData.length; i++) {
    series.push({"name" : key, "data" : sales[key]})
}

This constructed series array is part of the object which you must pass as argument to highcharts method.

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.

you can also refer to the fiddles which are available in their demo pages for each type of chart to know more on how to display a particular type of chart.
