[ncl-talk] Graphical error

Dear Sir,

Thanks for your kind help. I followed your instruction, tot_prc =
dim_sum_n_Wrap(prc,0) . I am getting errors when I used two-dimensional
TRMM 3B42 data. I got a map without precipitation which is in the
attachment.

For two dimensional data,
warning:Non-monotonic coordinate array generated -- check validity of the
aggregated (leftmost) dimension
sum_op_ncl : dim_sum_n over dimension(s): lat
(0) Error: scalar_field: If the input data is 1-dimensional, you must set
sfXArray and sfYArray to 1-dimensional arrays of the same length.
warning:create: Bad HLU id passed to create, ignoring it
warning:ContourPlotSetValues: Data values out of range of levels set by
EXPLICITLEVELS mode

When I added multiple files manually, it gives me a right map (in the
attachment).  I also tried to plot for three-dimensional data, but it gives
me following warning.

gsn_csm_contour_map_ce: Fatal: the input data array must be 1D or 2D

I am looking forward to your kind advice and positive response.

Cheers,
Jalal
