Scatterplot with three sets of values

I am running into difficulties with what should be a very simple chart, not sure what I'm doing wrong! I'm basically trying to mimic a simple scatterplot like you see here: http://vixcentral.com/cefexample/

I've attached the data with three values of data needed to replicate. This orange line for "12 Mo NAV Div Yield %" should actually be the X-Axis, that is what is throwing things off, but I cannot seem to get it to work as intended. Any ideas where I'm slipping up? THANK YOU!!
