Description

plpie plots a pie showing the relative contributions of values in values to their total. The segments are labeled with string of up to 16 characters stored in labels and two texts of variable size are placed over and under the pie. Usage in a simplot script needs a special treatment for the segment labels: these are not read like other arrays, but exactly n strings must be placed between the arguments n and r.
