generating plot based on xstart xstop values

so that at 0 the value is 5, at 2 the value will be 7 (point 1 value plus point 2 value), at 4 the value is 2

ideas on how to use excel formulas to accomplish; or VBA routines i could download ??

thanks

Hi Frank,

I didn't understand the problem atall. Can you send me the spreadsheet you with the data generated, and a clear description of the problem. I am not sure if the problem is clear to anyone or not, but for me, I am unable to understand the requirement. Can you please describe with a little more details?
