If I understand correctly, the OP has separate calls to get the data for the four lists. If so, what is the problem? Just assign the dataProvider as needed.
You are using result handlers, storing the data in instance variables, and not trying to bind directly to lastResult, correct?

If not, use a UNION query to normalize the data, then use a filter function to filter on grocery type and refresh the ArrayCollection. Icky method: If you have no control over the backend at all, then you can use something like myChart.dataProvider = nastyArrayCollection ;-) HTH; Amy
