Hmm, could be cool. I think people the most common way people would be configuring these widgets would be something like:

```javascript
dashboard.types().get('lastvalue')
  .title('foo')
  .x(function(d) {
    return d.time;
  });
```

The approach I showed here in the docs was to show how things could be set, but thinking about it now, it'll probably just confuse people, will remove it.
