I have a graph that has a sql data source defined, but I want to be able to hide the graph if there is no data being returned from the data source. I tried to bind the Visible property, but the Fields list is empty even though I have the data source defined and it is working fine when there is data. I thought I would be able to do Visible = Count(Fields.PatName) > 0 since PatName is a field being returned by the SQL data source.
