Currently you can bind against a datasource to pull values for a series, however if you want to specify a series as well via the datasource you cannot. This is a shame since it restricts the developers ability to do full dynamic results. 

Say for example you have a video and a poll / poll result beside the video. You cannot currently pull the poll from the server dynamically you sould have to re-create the chart from scrath using data already in the form (or do some nasty javascript building to get the chart working with series data through the datasource).
