I guess the problem I'm running up against is that: pd 'new' pd (sin;cos,: ]) range 1 7.5 0.5 pd *: 0.1*i.160 pd 'show'
works with either of the two middle statements, but not both together, the second obliterating the first. (Why not?) I want to superimpose two differently structured data items, one of which is able to form closed polygons but doesn't share the x-vector of the other one.
