I need some assistance with completing the final calculation (difference between 2 series) and presenting the results in a line chart. Attached is an spreadsheet with the data table structure, calculations, example parameters and the desired line graph. Attached is a tableau workbook as well. I have completed the problem up until 1) finding the difference between two series for the same observation date and forward month & 2) presenting the results (differences) in a line chart format by year.
Please contact me if you have any questions regarding the problem definition and underlying data structure. My phone number is 713-323-8981 or 713-204-5575. Thanks. David
