Computing Histograms with UDF's

Hi,

This is a followon from another question I asked a while ago.  I'm
calculating percentiles etc.. for datasets
and I wondered how I would do this with a histogram instead so it's more
efficient.

Does anybody have an example of this currently in the Pig source code or
some advice on how to go about
doing this.

Many thanks,
Jon.
