I am trying to create 2 graphs within a panel of the same series of data, where 1 is a subset of the other. Basically I want to create an overall and zoomed in view of the data. My goal is to have 1 graph's x-axis be a month and the other graph's x-axis be a year. Below is a graph that I have gotten as I want it with the exception that the axis are both on a year's scale. I would like the top graph to limit the data being graphed to where the data exists. Any suggestions for how to control the axis or create the graphs I am looking for would be appreciated.
