Bullseye Polar Data Plot

BULLSEYE plots patch data in polar coordinates. The DATA matrix is mapped to a bullseye plot as follows. The matrix rows are mapped to the circumference and matrix columns are mapped to radial direction. For example, the top-left (first row, first column) data point in the matrix is mapped to the inner-most radial patch and starts from 0 degrees (far right of bullseye, not top) and extends counter-clockwise.

If you use the hard coded cardiac anatomic lables then this first row is within the INFEROTLATERAL segment. The last row is within the INFERIOR segment.
