Re: plot formatting question

Hi Will,
Yes, you can use overlay with ppl commands - you need to use
"PPL plot/overlay"  when you've made the ppl settings and finally
go to draw the plot line:

   yes? plot/i=1:100 i*sin(i/6)
   yes? plot/over/i=1:100/set    i*cos(i/12)
   yes? ppl pen 1,4
   yes? ppl plot/over     !  /over to complete the overlay plot

Another hint is that setting up axis labels and so forth is generally done
only on the first plot command, and  so you might use PPL commands
on the first plot call and then regular plot/overlay commands with /DASH,
/COLOR, and /THICKNESS to set the features of other plot lines:

   yes? plot/i=1:100/set i*sin(i/6)
   yes? ppl labset 0.3,0.08,0.3
   yes? ppl axlabp, 1,-1
   yes? ppl  ylab "modified SIN"
   yes? ppl plot

   yes? plot/over/i=1:100/THICK i*cos(i/12)
   yes? plot/over/i=1:100/color=green/dash=(0.6,0.2,0.1,0.2) 10*sin(i/5)
