I also noticed the differences in the graphs. If you compare the one on the web site to the dendogram on the web site you'll notice they contain exactly the same information though. The bar graph is a sort of "filled in" dendogram. If I find time while I'm in Asia I might see if I can modify the dendogram routine to also return the correct data for the banner plot (a.k.a bar graph :-)). I also intend to convert the AC and dendogram calculations to functions. Ideally, it should be possible to call all of these routines multiple times without having to copy code. Finally, a lot of stuff needs to be dropped into collapsed areas so it's easier to scroll up and down the worksheet. and of course we need list boxes, etc to pick methods. I'll see what I can get done, but for sure nothing for the next week or so (until I get to Beijing).
