Adam,
Thanks for handling the gsn*String question.
As for moving the labelbar, you can do it by setting "vpXF" and
"vpYF". These values go from 0 to 1 inclusive, where (0.0,0.0)
represents the lower left corner, and (1.0,1.0) represents the upper
right corner.
Thus, to move the labelbar down, you might try setting vpYF to
something like 0.2 or 0.3. You probably don't need to adjust vpXF,
unless you don't want the labelbar centered in the X direction.
The other option, if you don't like the labelbar that gsnPanelLabelBar
is giving you, is to create your own. Here's a modified version of
the end of your script, where I turned off the panel labelbar, and created
one separately. It does involve more work, but it also gives you
more control:
...
end do
resPanel = True ; panel mods desired
resPanel@gsnFrame = False ; don't advance frame
resPanel@gsnPanelBottom = 0.05
resPanel@gsnMaximize = True ; fill up the page
resPanel@gsnPaperOrientation = "auto"
resPanel@gsnPanelYWhiteSpacePercent = 5
resPanel@gsnPanelXWhiteSpacePercent = 5
resPanel@txString = "Z700 Annual Average"
gsn_panel(pswks,plot,(/1,5/),resPanel) ; draw: 1-down , 5-across
;
; Get information about contour levels, and fill colors
; used so we can use this in the labelbar.
;
getvalues plot@contour
"cnLevels" : levels
"cnFillColors" : colors
end getvalues
x = 0.1 ; X position of labelbar
y = 0.4 ; Y position of labelbar
lbres = True ; Set up labelbar resources.
lbres@vpWidthF = 0.8 ; Change width and height
lbres@vpHeightF = 0.2 ; of labelbar.
lbres@lbOrientation = "Horizontal"
lbres@lbPerimOn = False
lbres@lbFillColors = colors
lbres@lbMonoFillPattern = True ; Use solid fill, not patterns
lbres@lbLabelAlignment = "InteriorEdges" ; default is "BoxCenters"
lbres@lbLabelFontHeightF = 0.01
lbres@lbTitleString = "700 mb Geopotential Height"
lbres@lbTitleFontHeightF = 0.015
nboxes = dimsizes(levels)+1
labels = new(dimsizes(levels),string) ; Convert levels to strings.
labels = levels
gsn_labelbar_ndc(pswks,nboxes,labels,x,y,lbres) ; Draw labelbar
frame(pswks)
end
