Subject: Re: Number of subscripts do not match number of
dimensions of variable
To: Mary Haley <haley@ucar.edu>
Hi, thanks again for your kind help, however, the script is working now,
but unfortunately the plot is very strange (attached) it is not a simple
line. I just include in your previous response, then it was working:
dimwx = dimsizes(wx)
nsn = dimwx(0)
nwe = dimwx(1)
np = dimwx(2)
x = onedtond(ndtooned(wx), (/ nsn*nwe, np/))
y = onedtond(ndtooned(py), (/ nsn*nwe, np/))
Because the error was appeared np is not defined
Regarding Mary response, this is already staggered as indicated in the
printVarSummary.any further suggestion will be highly appreciated.
Thanks again for your help and time
wei
