How can I find the max cell value in a collection of objects using lodash while ignoring one of the keys.

```
var data = [{
            tick: 0,
            valueA: 3,
            valueB: 2
        }, {
            tick: 6,
            valueA: 6,
            valueB: 3
        }, {
            tick: 12,
            valueA: 2,
            valueB: 4
        }, ...];

```

I want to find the max tick, this is the row identifier, and the max of all *other* values. What I have so far is:

```
var maxTick = _.max(data, 'tick'),
    maxValue = _.max(data, function(o) { return _.max(_.values(o))};);

```

How can I let `maxValue` ignore the tick data?
