You could first map over the array and get the values and then flatten the result:

var result = _.flatten(_.map(arr, _.values));

var arr = [{Analytics:16}, {Technology:12}, {Medical:20}, {Operations:40}];
var output = [];

_.each(arr, function (e){output.push(_.flatten(e)[0])});

output = [16, 12, 20, 40];

_.reject(_.pluck(arr, "Medical"), function(val){ return _.isUndefined(val) }) for getting medical

var arr = [{Analytics:16}, {Technology:12}, {Medical:20}, {Operations:40}];
_.map(arr,function(m){return _.values(m)[0]});
