How to create multiple series on dx-Chartjs

Question

I am trying to visualise some ratings based on their type however I am having difficulty finding how to group the series based on the types.

the chart options are as follow:

$scope.chartOptions = {
            dataSource: data,
            commonSeriesSettings: {
                argumentField: "ratingDate"
            },
            series: [
                { valueField: "score", group: "Recommend", color: '#66cc33' },
                { valueField: "score", group: "Service", color: '#35a2f4' },
                { valueField: "score", group: "Product", color: '#ef4e3a' },
                { valueField: "score", group: "Experience", color: '#fea000' }
            ],
            argumentAxis: {
                grid: {
                    visible: true
                },
                argumentType: 'datetime'
            },...

the series option has no group option, its what I wish I had as I would like to see one series being about the scores of Service over time, one about Product score overtime etc.

Currently I get 4 duplicated series with different colours. Here is a fiddle

The documentation has no information about grouping like this so I was wondering if anyone has come across this and solved an issue similar to this?

Maybe a grouping function that I can return truMetric == "Recommend" in?

My sample data looks like this:

var data =
            [

Solution

You can use this: http://phonejs.devexpress.com/Documentation/Howto/Data_Layer?version=13_2#Data_Layer_Reading_Data_Grouping

var dataSource = new DevExpress.data.DataSource(data);
dataSource.group("ratingDate","truMetric" );
dataSource.load().done(function(result) {
    var chart_data=[];
    for(var i=0;i<result.length;i++){
        var d={ratingDate:result[i].key};
        for(var j=0;j<result[i].items.length;j++){
            d[result[i].items[j].key]=result[i].items[j].items[0].score;
        }
        chart_data.push(d);
    }
$("#chartContainer").dxChart({
    dataSource:chart_data,
    // rest of your code

        series: [
            { valueField: "Recommend", name:"Recommend",  color: '#66cc33' },
            { valueField: "Service", name:"Service",  color: '#35a2f4' },
            { valueField: "Product", name:"Product", color: '#ef4e3a' },
            { valueField: "Experience", name:"Experience",  color: '#fea000' }
        ],

//rest of your code
