[Solved]-highchart - how to encapsulate multiple series to one series as their parent-Highcharts

In general it's not easy task but possible to achieve. Crucial option is threshold which sets translation you need. However, only one threshold per series is supported. Then to overcome that issue, we will use for each category different series, but connected to the first one using linkedTo. Demo: http://jsfiddle.net/hNkAA/7/

In short, main series:

    {
        name: 'data1',
        id: 'data1', //set ID for children series
        data: [-12], //one series = one point for category
        stack: 0,
        index: 1,
        //legendIndex: 0,
        dataLabels: {
            enabled: false
        }
    }

And connected series with different starting point:

    {
        threshold: 10, //base for that series will be 10, not default 0
        name: 'data1', 
        linkedTo: 'data1', //link to master series
        data: [[1, -10]], //set point only for second category
        stack: 0,
        index: 0,
        //legendIndex: 1
    }
