Most here know about how I learned to hate Access graphing. M$ will never make Access graphing as good as Excel. If they did, perhaps you wouldn't buy Excel and those guys would complain.
I would push db data to a dynamic named range in Excel and use Excel graph tool, or perhaps link the db data in xl. Thing is, I don't know if the latter will pull in the entire table without modifying what import spec when records are added/deleted but I know the former method works.
EDIT - what I didn't have to do was show the graph in any Access form or report but that shouldn't be too hard? Instead my process provided the option to open the graph file whenever it needed to be retrieved. That also made it easier for management to print the chart, which is what they wanted. A form that displays the chart is somewhat pointless in that case.
The more we hear silence, the more we begin to think about our value in this universe.
