Comparing Individual to aggregated group

I currently have a graph with aggregated values by four regions. They individuals which make up the regions are based on facilities. There are slicers for year, size and the type of corporation. I would like to filter for an individual facility to compare to the different regions. 

Currently, I have two graphs. One is transparent, and I have edited the interactions to allow a drop-down to select the individual facility. Behind that graph, I have the graph with the regions and the ability to filter those different regions. I have set the min and max on the y-axis so they are on the same scale. This works, but doesn't provide an effective graph if the difference is not very large. Is there a way to syncronize the y-axis or would there be another visualization to improve this? Thank you.
