Highcharts Pie Chart Drilldown not showing on third drill

Question

I have two issues:

1. The third drilldown the names of the DataLabels appear as \"Slice\" instead of their respective names. Is this a bug or do I need to specify

Answer 1

Check out this fiddle or use the following code in the drilldown part:

data: [
    ['slice_name',10],
    ['slice_name',7],
    ['slice_name',33],
    ['slice_name',2]
]
