Here is jsfiddle. It has categories and each category has more than 1 data. What I want ? I have categories but each category doesn't have data. There is only 1 slice that have data for outer pie.

Answer 1

Here is working Demo

Actually you need to remove drilldown attribute from the pie that has no link with donut pie and check the data with:

 if(data[i].drilldown!=undefined){
    for (var j = 0; j < data[i].drilldown.data.length; j++) {
        var brightness = 0.2 - (j /data[i].drilldown.data.length) / 5 ;
        versionsData.push({
            name: data[i].drilldown.categories[j],
            y: data[i].drilldown.data[j],
            color: Highcharts.Color(data[i].color).brighten(brightness).get()
        });
    }
}}

or put empty drilldown like this Demo
