I have data from a program that gives me surface concenteration between a given set of latitudes and longitudes. I am looking to plot these onto a map in matlab using usamap and states as defined in matlab example 2 of the usamap command. The problem is that the data from the program is rotated by about 9 degrees, and so far I have been unable to find a way to rotate the usamap & the state boundaries by 9 degrees about the center of the map. Is there a way to do this? Any help\hints in this regard would be deeply appreciated.Thanks in advance.
