Creating array with key and values from objects with AngularJS and LoDash

I'm attempting to use Angular-Chart in my AngularJS app.

From the documentation, I see that you can define Labels, Series and Data like this:

$scope.labels = ['2006', '2007', '2008', '2009', '2010', '2011', '2012'];
$scope.series = ['Series A', 'Series B'];

$scope.data = [
  [65, 59, 80, 81, 56, 55, 40],
  [28, 48, 40, 19, 86, 27, 90]
];

My problem is that in my case, the labels are key values from objects, and series and data are value and property from such objects.

For instance, given the following example:

Labels would be: ['324', '369', '391', '396', 'KE-22'] (Key from all objects in Cars)

Series would be: ['Trips','Total'] (Value from Cars)

And Data would be (Property from Cars):

[
   ['1','4','5','3','7'],
   ['00:00:08','00:00:13','00:00:24','00:00:03','00:00:01']
]

Is there some way I can create such arrays?

Right now I create the objects using LoDash, like so:

dataByMonth = _.mapValues(dataByMonth, function(month) {
    var obj = {};
    var carArray = [];
    carArray = _.groupBy(month, 'car');
    obj.Cars = _.groupBy(month, 'car');

    obj.Drivers = _.groupBy(month, 'driver');

    _.each(obj, function(groupsValue, groupKey) {
        obj[groupKey] = _.mapValues(groupsValue, function(groupValue) {
            return _.reduce(groupValue, function(sum, trip) {
                sum['trips']++;
                sum['duration']+= moment.utc(trip.duration, 'HH:mm:ss');
                sum['total'] = moment.utc(sum.duration). format('HH:mm:ss')
                //addDuration(sum.duration, car.duration); 
                return sum;
            }, {trips: 0, duration: 0, total:0})
        });
    })

    return obj;
});

$scope.statistics = dataByMonth;
