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: http://rapidgator.net/file/29594247/20201_23405_50502.XLS.html Here is a link to an example contour plot, made in another program (SAS): http://rapidgator.net/file/29594680/50502_20201_23405.png.html 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, Nicholas Kormanik
