1. I assume you have triggers loading the data
2. Is there a place where you can actually select a row to initiate the Selected Row assignment? To me this seems like it may not work, or may not work right. Right now you are saying that from what you are displaying, in that source, each time I switch to another row selection you might be binding a different account type to be displayed. However your actual chart data and the series to display data seems to be in a single source. I would split that out so you have a separate source to drive selection vs. display data.
