Show calculated plot first then actual plot of output array

I am trying to create a vi that will allow the user to adjust the values to create a ramped array and show it on a graph.  Then when the user presses a start button the actual output is displayed on top of the calculated plot.

Eventually the user will be able to chose between and input a csv file with captured data from an operation instead or use the rampgenerator.vi.

I have tried many variations over the last couple of days.  I am not sure what the correct approach is.  Just a couple of weeks ago I completed LabVIEW Core 2 and feel I am over complicating things.

Any help would be greatly appreciated, thanks
