Annotation Chart - Annotations overlap the time-series graph.

[Pei]

When I add annotation title and annotation text in my dataset, the annotations just overlap the time-series graph.

Annotation chart with annotations

Annotation chart without annotations

For the graph options, I didn't change 'displayAnnotations', which is defaulted to 'true'. I am running out of ideas what might cause this issue. Any advise is welcome :)

The AnnotationChart doesn't (yet) know about the annotation and annotationText roles.  It assumes the string column following a data column is annotations.  

It should be possible to support the same roles as all the rest of the corecharts.  We just haven't had any requests to do so, until now.
