Thanks to the code from Ivan Memruk at Mind The Robot, and refinements done by Freddy Martens at atstechlab, I made some additional tweeks to get a reasonable detail gauge for the weather.
I still have more work to do on the details, the current code, although very flexible, makes a lot of implicit assumptions about the values the gauge will have, and the resulting geometry of the face. So, for instance, you can’t get a 300 degree thermometer face, and have the hand point at the right spot, just by changing upper/lower values, and tick mark settings.
