donut3

Creates a 3-D donut chart with offset slices and custom labels using pie3 syntax and removing vertical edge lines in the same slice.

The pie3 chart in Matlab could not be plotted in a donut style (with an area of the center cut out). This function creates a 3-D donut chart by changing patch and surface vertices of the pie3 chart. Thus, it maintains all the syntax and editable properties (offsets slices and specifies the text labels) of pie3 function. It could be used to display 3-D proportions or cyclic colormaps. The ring width of the donut is adjustable so you will get a pie3 chart if set the ring width as 1. In addition, vertical edge lines in the same slice are removed.
