[ncl-talk] PDF appearance and number of bins used

[Sri nandini]

Hello ncl-users,

I am plotting a PDF, for a particular location with relative frequencies 
that are calculated based on counts of the SSH anomalies between-25cm 
and +25cm, using a bin width of 0.5cm based on 100 bins used.

Using this i calculated and plotted a global PDF which results in nice 
smooth curve (also attached here).

But when i used a specific location, e.g New York, using the same method 
as above, the PDF curve appears very rough/ragged.

Is this also because of the data distribution and not only dependent on 
the number of bins used?

How can i further smooth this curve, result attached. I have tried to 
play around with the bin bounds, and number of bins used (25,50,75). 
Using bin =25 results in slightly more smooth PDF but the amplitude of 
the percentage % increases dramatically...

Sri
