I have two issues:
I played with the first A data section, and changed it to this:
data: [{
y: 33.06,
name: 'A',
drilldown: {
name: 'Budweiser',
data: [
{name:'A', y:10838}
, {name:'B', y:11349}
, {name:'C', y:11894}
, {name:'D', y:11846}
, {name:'E', y:11878}
, {name:'F', y:11662}
, {name:'G', y:11652}
],
color: colors[0]
}},
This is working perfectly for me. I pulled the categories and data nodes into a single array of name/data object nodes in the data array. Check the updated jsfiddle to see how the changes worked.
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]
]
