I've been attempting to create a contour plot within Mathematica 8.04.

I posted to the Mathematica StackExchange, but didn't get a conclusive
answer:

http://mathematica.stackexchange.com/questions/8821/creating-optimal-smoothe
d-contour-type-plots-x-y-z-using-mathematica-8-04

Hopefully someone here can assist.

Here is a link to the data file:

Here is a link to an example contour plot, made in another program (SAS):

In case the files do not make it through to you, the data file is an Excel
.xls file with three columns, X,Y,Z.  Z in the contour plot would be shown
by contours or a gradient of colors.

If a contour plot isn't possible, perhaps ListPlot3D?

The key sticking points are to get the data into Mathematica, and then to
create the plot.

The process is far from straight-forward.  Definitely a learning curve
involved.

Unfortunately the Mathematica documentation almost exclusively gives
examples using functions and distributions, not standard data columns for
input.

Thanks,
