Systems and methods are provided for drawing a wedge from an array of data. An angular reference table contains a plurality of angle values. An angle sampler samples a subset of angle values for a given arc of a plurality of arcs that will constitute the wedge from the angular reference table to provide an even sampling along a representative portion of the arc. A pixel locator determines horizontal and vertical coordinates for each of the sampled angle values. A pixel indexer determines an associated row and column of the two-dimensional array for each of the sampled angle values and retrieves a color for each of the sampled angle values from the two-dimensional array. A graphical renderer draws pixels with the retrieved colors at the determined horizontal and vertical coordinates.
