This question led to a new package:
Is there a way to draw Kiviat diagrams easily?
The first example uses three macros with arguments. First, you create a spider, then you can create a kiviat polygon and you can create graduations
Another solution is to use an external file with data
The tableae.dat file is used with the package pgfplotstable.sty
I'd go fot the
Have a look at this example.
I've written a crude set of macro's that might help you on your way when making your own (adjust these and you should be fine).
I'm not that great a programmer myself so perhaps someone else will come up with something much more refined but this will do for now. The upside to my little programming skills is that the code is easy, so you'll probably be able to grasp it quickly and adjust it to your needs.
There are 4 macro's. The main macro is
Add this to preamble:
As said above, you will need to adjust the drawing commands to fit the number of axis. This means adding
You can also adjust the number of nodes on each axis by adjusting the
I've also made an example of how to actually draw the spider chart:
Hope this helps!
With the current pstricks-add.tex you can simplify it:
