Title: Adding many metrics causes current value to not display

This manifested itself when I added the fifth metric to a dashboard which was showing the last five minutes of data. After adding the metric all graphs would display the red 'NF' with the graph behind displaying correctly.

The console (in Chrome) displayed:

```
tasseo.js:45: Uncaught TypeError: Cannot read property 'y' of undefined
tasseo.js:51: Uncaught TypeError: Cannot read property 'y' of undefined
```

The code submitted fixed the issue for my situation so even if the code isn't what you'd like hopefully it'll help!
