I am having trouble getting a named range to work in an Excel 2013 scatter graph. The graph is a stress-strain curve and I want the user to be able to determine the start and end of the linear portion to determine the stiffness of the material. The data is in columns C and D. I am using named ranges (Stress and Strain) that look like this: =Indirect(concatenate(............)) The indirect concatenate function is working because if I enter it in a cell with the reference start and end rows the same it reports the value in that cell (and if I add a sum function over a range it sums correctly). So basically I know that my named ranges work. However, when I try and add them to a scatter graph I continue to receive error messages.
Any help would be greatly appreciated.
