[ncl-talk] printing spi

[Dennis Shea]

The error mesages is telling you the exact problem:
   fatal:Plus: Number of dimensions do not match, can't continue

spi has 4-dimensions:
   [len | 7] x [time | 1368] x [lat | 4] x [lon | 9]

prc has 3-dimensions
   [time | 1368] x [lat | 4] x [lon | 9]

yyyymm has 1-dimension
   [time | 1368]

==============
The print statement you used was copied from:
    https://www.ncl.ucar.edu/Document/Functions/Built-in/dim_spi_n.shtml
    Example 2
That was working upon a single time series prc[*]



You have a 4-D array. *You* must make the appropriate changed to handle
your situation.
The eamples are not generic to all dimensions.

   nlat=4
   mlon=9

   do nl=0,nlat-1
      do ml=0,mlon-1
       print("------------------------------------------------")

print(yyyymm+sprintf("%8.2f", prc(:,nl,ml))   \


                +sprintf("%8.2f", spi(0,:,nl,ml))+sprintf("%8.2f",
spi(1,:,nl,ml)) \

                +sprintf("%8.2f", spi(2,:,nl,ml))+sprintf("%8.2f",
spi(3,:,nl,ml)) \

                +sprintf("%8.2f", spi(4,:,nl,ml))+sprintf("%8.2f",
spi(5,:,nl,ml)) \
                +sprintf("%8.2f", spi(6,:,nl,ml)))

    end do
  en do
