Re: drawing lines through cell centres on a map

Hi Mark,

Actually with a little variation on Mary's script it is possible to
keep multiple windows on the screen in a script run on the command
line as well. The trick is simply to set wkPause and gsnFrame back to
True for the last window you draw to:

load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_code.ncl"
load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_csm.ncl"

x = (/10.,20.,30.,40.,50.,60.,70.,80.,90./)
y = (/0.,0.71,1.,0.7,0.002,-0.71,-1.,-0.71,-0.003/)

type = "x11"
type@wkPause = False

wks1 = gsn_open_wks(type,"xtest1")
type@wkPause = True
wks2 = gsn_open_wks(type,"xtest2")

res = True
res@gsnFrame = False

plot1 = gsn_csm_xy(wks1,x,y,res)

res@gsnFrame = True
plot2 = gsn_csm_xy(wks2,x,y+5,res)
