Abstract
Apparatus for displaying the information represented by data samples occurring along radial lines at display points arranged in rows and columns wherein intermediate interpolated data values are derived at the intersections of a row containing a display point for which a final data value is sought with radii on either side of the display point and interpolating the first and second intermediate interpolated data values so as to derive a final interpolated data value at the angular position of the display point with respect to the radii.
