Hello,

I need to display a chart binded dynamically with multiple series of the same object type.

I managed to do that using the following chart parameters :

dataSource: {
    data: data,
    group: {
        field: "group"
    }
}

where my data looks like this (this is only an example, data is actually:

var data = [{
    group: "First",
    category: 1,
    value: 100
},
{
    group: "First",
    category: 2,
    value: 200
},
{
    group: "Second",
    category: 1,
    value: 200
},
{
    group: "Second",
    category: 2,
    value: 400
}];

 

However, this structure doesn't suit my other needs (such as displaying a table with one row per group), so I'd like to know if it's possible to display the same chart using data as following :

var data = [{
    group: "First",
    values: [{
        category: 1,
        value: 100
    },
    {
        category: 2,
        value: 200
    }]
},
{
    group: "Second",
    values: [{
        category: 1,
        value: 200
    },
    {
        category: 2,
        value: 400
    }]
}];

 

How can I do that ?

Thanks a lot for your help.

Best regards

Seems like I erased one part of my post :

Hello,

It is possible with some code to convert the data items to series configuration - example.
