Hi,

You can only attach lines to one plot object at a time, so that's why plot(0) works and not plot. But, I can see why it would be useful to be able to pass an array of plots, so I'll add this to our list of things to do.

Meanwhile, you will need to make "dum" big to be (# of plots) x 4:

nplots = dimsizes(plots)
dum = new(nplots*4,graphic)

do i = 0 , 3
    do n=0,nplots-1
     dum((i*4)+n)=gsn_add_polyline(wks,plot(n),xpts(i:i+1),ypts(i:i+1),resp)
    end do
 end do
