Display.Radius "Hole"

Greetings,

I finally figured out a way to map my terrain data from a cartesian grid to a radar-centric polar grid (This makes my data processing easier to code and hopefully more efficient). I'm trying to display the data using Display.Radius and Display.Longitude since the data are now in a polar grid. Is there any way to eliminate the "hole" at the center of such a plot? The cursor coordinates within this hole (using the standard middle mouse button readout) display an area of range < 0;

I have a sample program and associated terrain file at:

ftp://ftp.nssl.noaa.gov/users/kmanross/

(you'll need to unzip the .nc file).
Thanks!!

-kevin.
