[Plplot-devel] plenv() axis parameter

Is there any bit arithmetic behind this from the manual: axis = -2: No box or annotation. axis = -1: Draw box only. axis = 0: Draw box, labeled with coordinate values around edge. axis = 1: In addition to box and labels, draw the two axes X = 0 and Y = 0. axis = 2: Same as axis = 1,
