PDF calculation for a grid node

Dear ncl users,

I would like to calculate the pdf of wind speed for a grid node.

When I calculated it for a grid point everything went well.

The number of bins, and the maximum wind speed for each grid point have been
estimated correctly (line number 92, 89 respectively), for each grid point
throughout the time period (10957 records)..

Moreover, the printVarSummary for max_ws1 and nbins give me the dimensions..

Number of dimensions 3 (1 x 19 x 17) -> (height x rlat x rlon)

As you can see at the attached script, I tried to solve the problem using do
loops but unfortunately without success.

Has anyone got any idea, how to calculate the pdf for each grid point..

Any help would be appreciated..

Ioannis
