[ncl-talk] contour plot: explicit tickmark labels and repositioning XBString

[Tabish Ansari]

Hi

I'm trying to make a contour plot from a 12x12 matrix which I'm reading
from a table. The x and y axes are automatically labelled from 0 to 12
based on the default index numbers of the data (0,11). However, I want to
explicitly define tickmark labels starting from 0 to 120 with each grid
representing a change of 10 units. I tried using *res at tmXBMode  =
"Explicit" and res at tmXBValues = ispan(0,120,10) *but that then shows only
two tickmarks (0 and 10) adapted to the index numbers. I have pasted my
script below and attached the plot.






































*load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_code.ncl"load
"$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_csm.ncl"beginncol = 2 ; THE TWO

"Parameter 1"  res at cnFillMode          = "RasterFill"
res at cnLinesOn           = False  ;res at tmXBMode            = "Explicit"
;res at tmXBValues = ispan(0,120,10)  plot = gsn_csm_contour(wks,a,res)  ;
Create filled contoursend*

Also, I want to shift the X-axis label above the legendbar.

Any help would be appreciated.

Thanks,
