MELMEL,
What have you checked in your set up so far and is the chart embedded or on
a sep. sheet? Is it raw or calculated data that you are trying to update?
Make sure that you data range includes the cells that you are updating. It
should automatically update.

Is there anyway to have Excel automatically update an existing chart after

through the process of creating a new chart everyday I change / add data.
