Mathgroup:

I have a 2-D list of data.  That is, { {1.5,3} , {2.34,1} ,.... } for =
example.

Is there a package out there that divides up the XY plane into bins, =
then counts the number of times the above points fall into the
different = bins.

I imagine the following picture:

A 3-D picture where the heights at different bins are the relative =
frequency of the points contained in the bin.  This is just the
analogue = to the 2-D histogram when the data above is only one
dimensional.

I tried the histogram package at mathsource, but it seems to only work =
with one-dimensional data.

Thanks in advance,

Chris Farr
