using "getvalues" on a panel plot

Hello,

I am trying to create a panel plot and want to display a common title that
is aligned with the left edge of the panels. I would like to use
"getvalues" to automate this process, as the size & location of my panels
change with each plot and manually entering the x-position each time gets
very tedious.

A sample of my code is below. When I use "getvalues" on plot(0) -- the
top-left plot on the panel, the retrieved vpXF value does not match any of
the values displayed from gsnPanelDebug. Can anyone provide some insight
on this? Thanks a lot!

do n=0,5
 res@gsnRightStringFontHeightF = 0.025
 res@gsnRightStringOrthogonalPosF = 0.02
 res@gsnRightString = rightStrings(n)
 res@gsnLeftStringFontHeightF = 0.025
 res@gsnLeftStringOrthogonalPosF = 0.01
 res@gsnLeftString = leftStrings(n)
 plot(n)=gsn_csm_contour_map(wks,data(n,:,:),res)
 end do

 getvalues plot(0)
 "vpXF" : xloc
         "vpYF" : yloc
 end getvalues
 panel_res = True panel_res@gsnPanelDebug = True
panel_res@gsnPanelRowSpec= True panel_res@Maximize= True
panel_res@gsnPanelXWhiteSpacePercent = 2.
panel_res@gsnPanelYWhiteSpacePercent = 2. panel_res@gsnPanelCenter = False
panel_res@gsnPanelBottom = 0.05 panel_res@gsnPanelTop = 0.95

panel_res@txString = title
 panel_res@txFont = 21
panel_res@txFontHeightF = 0.018
 panel_res@txPosXF = xloc
 gsn_panel(wks, plot, (/2,2,2/), panel_res)
