[ncl-talk] 2nd axis with Boxplot

Hi Frank,
No there is not. However, you could use the vpXF/vpYF/vpWidthF/vpHeightF
resources to set exactly where you want the boxplot to be drawn, and then
specify the same resources, turn off all borders/tickmarks/labels except
the Y-Axis, create a blank plot using gsn_csm_blank_plot, and draw one on
top of another:
https://www.ncl.ucar.edu/Document/Graphics/Interfaces/gsn_csm_blank_plot.shtml

Tick mark example #11 is similar, but overlays one plot on another using
the overlay procedure.
http://www.ncl.ucar.edu/Applications/tickmarks.shtml#ex11
You will not want to use overlay, but you will want to set gsnDraw = True
(=default) and gsnFrame = False in both resource lists.

bres = True   ; boxplot resource list
bres at gsnFrame = False
bres at vpXF = 0.2
bres at vpYF = 0.8
...
plot = boxplot(....

res = True   ; blank plot resource list
res at gsnFrame = False
res at tmYUseLeft = False
res at tmYROn = False
res at tmYRLabelsOn = False
res at tmXBOn = False
res at tmXBLabelsOn = False
...    ; other tm resources may be needed.
res at trYMinF = ..
res at trYMaxF = ..
res at tmYLMode = "Explicit"
res at tmYLValues = (/.../)
res at tmYLLabels = (/.../)

bplot = gsn_csm_blank_plot(...
frame(wks)

Hope that gets you going in the right direction!
Adam
