Rather than adding the `text` function inline like this... you could replace the `text` function of this component in `graphBuilder.create()`  *after* [addInternalComponents()] (https://github.com/racker/glimpse.js/blob/9e4751accb9c2fc16f70f7a9520fc1f1bd8f6188/src/graphs/graph-builder.js#L234) gets called.

Something like this should work:
```javascript
addInternalComponents(g);

var unit = g.config('yAxisUnit');
g.components('gl-stats').text = function(d) {
  return 'Avg: ' + d.avg + unit + 
         '    Min: ' +  d.min + unit +
         '    Max: ' + d.max + unit;
};
```
