4D Charts?

Anyone know of a plugin for Excel that provides the ability to plot 4 data dimensions on a single chart?

Specifically I want to chart:
x-axis: priority (4 distinct values possible)
y:axis: severity (4 distinct values possible)
z-axis: phase (5 distinct values possible)
plot-point: a number, representing the number of data values for the x-y-z plot

I'm not stuck on using x-y-z axis as above, nor do I have a particular preference for chart type (bar, plot, etc), but I suspect some kind of bar would be more readable. The above is for example only.

I'm having trouble visualizing that, but can you use color or patterns to convey your fourth axis?

Look up "heat map" - that's a 2-D map (usually geographic) representing 3-D data. Use color for your 4th dimension and you'll get a 3-D heat map. BUT I'm not sure how usable it will be.

You might want to reexamine your premises...

With Panopticon Spreadsheet Mapper, you get a powerful tool for visualizing data in three dimensions simultaneously. The parameters can be changed on the fly. The technology is known as heat maps or tree maps, and the Spreadsheet Mapper plugs into Excel like an additional toolbar, so any data you can import or query into Excel is available for immediate visualization.

Check out the XLColorMap at http:\\

It is an Excel add-in which uses a color scale for the third dimension. It's a free download.
