[ncl-talk] adding legends to xy plot

[Tabish Ansari]

Hi

I am using the following script:

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

begin
 a     = addfile ("consolidated_d04.nc","r")
 wks   = gsn_open_wks ("x11","xy")                ; open workstation
 res                  = True                     ; plot mods desired
 res at tiMainString     = "PM2.5 at Mandir Marg"          ; add title
res at xyLineColors      = (/"blue","red"/)          ; change line color
res at xyDashPattern = 0               ; Make curves all solid
res at xyLineThicknesses = (/2.0,2.0/)               ; make 2nd lines thicker
res at pmLegendDisplayMode    = "Always"            ; turn on legend
res at xyExplicitLegendLabels = (/"Sim.","Obs."/)         ; create explicit
labels

time = fspan(0, 48, 49)
data = new((/49,49/),"float")
PM25_sim = a->PM25(:,0,38,37)
PM25_obs = asciiread("PM2_5_MM.txt",(/49/),"float")
data(0,:)= PM25_sim
data(1,:)= PM25_obs
 plot  = gsn_csm_xy (wks,time,data,res) ; create plot
end


However, I ​
​am not getting the desired legend names.

Please help me out

Thanks a lot

Tabish​
