A question about resource tmXBMode

Hi, all,

I have a question about resources of tmXBMode and tmYLMode. I tried to plot
the contour of a 31*32 array using gsn_csm_contour with explicit tick mark
mode. However, the figure looks wrong. First, the X-axis and Y-axis labels
do not show. Also the location of colorbar is not right also. Could someone
help me with this question? Thanks much!

P.S. The code:

load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_code.ncl"
load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_csm.ncl"
load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/contributed.ncl"
load "$NCARG_ROOT/lib/ncarg/nclscripts/wrf/WRF_contributed.ncl"
