In highstock addPoint needs to have the shift parameter set to true to work.
This example http://jsfiddle.net/pbDXn/ uses true (the last parameter)

1. Change the last parameter to false
2. Click add to add a point without shifting

Result: The chart goes blank. Clicking a few more times results in exception
```Uncaught TypeError: Cannot read property 'length' of null```

Expected: The points to be added.
