y = (/0., 0.7, 1., 0.7, 0., -0.7, -1., -0.7, 0./)
                 
;-- open a workstation
wks = gsn_open_wks("png",get_script_prefix_name())

;-- set resources
res                  =  True    ;-- generate an res object for plot
res@gsnMaximize      =  True    ;-- maximize plot size

;-- draw the plot
plot = gsn_csm_xy(wks,x,y,res)
