Hi Don, thanks for forwarding this. The thing is we've established the dartboard presentation showing indicators as segments (so data points aren't randomly placed).
The question we're struggling with is how do we move to stave charts using the same banding, but expressed in linear form? I've only heard the term "stave graph" via the (brilliant) Italians so it may be known as something else.
For anyone who might be interested, here is an example of a "stave" plot done in Tableau.
The basic approach is to create a circle plot with your sections and their stave items added in columns, and your response in the rows. Then you want to create a series of parameters set at the y-axis values where you want to have your colour zone breaks, and then create reference bands with values from and to each of these breaks (probably setting the labels to 'None' as you go...).
See my toy example here...
