# [ncl-talk] Panel plots direction (top to bottom first, then left to right)

```There are a couple ways you can do this in the looping sense. You can
re-arrange the plots in the gsn_panel call...

gsn_panel(wks,(/plotpanel(0),plotpanel(4),plotpanel(1),plotpanel(5),..../),(/4,2/),pres)

Or you could devise a counter that would handle this alternation with a bit
of math, and then just assign each plot to the graphics array per its panel
index.

panel_idx = ((phase-1)%2*4)+((phase-1)/2)
plotpanel(panel_idx) = plot

P.S. make sure ncl-talk is in your reply-to when you respond (usually a
reply-all works just fine), just so everyone can keep up with the
conversation and others can help as well.
