Small charts with 1 data item generate an exception

Steps to reproduce:
1. Link an arraycollection with 1 object in it to a cartesian chart
2. Make the chart very narrow (can happen when the user resizes a pod or another type of container holding the chart)
(if have the impression that this also can occur when the chart hasn't been visualised yet but I'm not sure about that)

Actual Results:

TypeError: Error #1009: Cannot access a property or method of a null object reference.
