I am trying to graph two sets of information. 
One data set that I want displayed as a flat line as drawn in the screenshot below.
The other data set will be the actual result which I would like displayed as a data point (again displayed in the screenshot). 
I have also included a screenshot of the source data for reference. I have 2 columns / mo. One column is the actual and the other column is the 100% for each month.
Is this possible?
