I would like to be able to use a formula in an Excel 2003 graph, to
dynamically modify the source and lable data of a graph based on a cell
reference.

For Example:
When I enter the number 1 into cell "a1" I would like to have the graph
automatically change to show the map points related to report 1, when I enter
2 inot "A1", I would like the source data to change to show points related to
report 2.

How can this be done?
