How do I change the graphing features to show the new data that has been entered?
Actually, the graphing features should automatically show the new data. What happens is, as you change the input data, the result data automatically renews itself, and so do the graphs. If this is not the case, then check to see if you changed the source data used by the pre-configured excel charts. If you changed the source data for the charts, or edited their format in certain ways, you will need to reformat the source data by right clicking over the graph and re-referencing the data from which each graph originates.
