Thank you Jim, I had a liitle off-list conversation with Greg and finally I got the solution. All the code is now on http://commons.wikimedia.org/wiki/File:Sonnenstand.png I got the workaround with my own "(sun)lines" function which does the shift from cartesian coordiantes to polar coordinates. An example result is attached. The negative vales where just a stupid try from my side, it does of course make no sense. Best, Thomas
