We could use helpers.callback here:
var items = helpers.callback(options.generateLabels, [me.chart], me) || [];

actually, turns out that that won't work because helpers.callback doesn't return the result of the callback.

We could change the callback method to return the fn result:
callback: function(fn, args, thisArg) {
if (fn && typeof fn.call === 'function') {
return fn.apply(thisArg, args);
}
}
