[Radiance-general] Sun charting program?

[Fitzsimmons, Rob]

I have run across a few times on the web, diagrams that show the sun position over the course of say 6 months.
I can't recall what that chart-type is called, but it looks somthing like this:

I used a tool from University of Oregon, 
http://solardat.uoregon.edu/SunChartProgram.html

then Photoshop'd my obviously fake green line indicating the sun's position.
They show up in these figure-8 patterns.

Anyone know a way to produce them?

Thanks
Rob F
