This takes care of the data in the worksheet but how to utilize the named formulas in the chart?
The easiest way to create the chart for this example is by using the existing data in SalesInfo sheet. Create the chart and then edit the =SERIES() formulas for each data point in the chart itself as shown here. Note: To edit each series formula: in the chart click on (in our example) each column in turn that represents a series and you can edit the formula for each in the formula bar.
