How can i make a battery indicator like a fuel level with a arrow? I know that i can give a arrow a tag to rotate on battery level. But i want to limit the rotation between two points. like from 290 degrees to 70 degrees for example.
Well assuming you mean -70 by 290, you just need to scale it to cover 140 degrees, like this: ((1.4*#BLN#)+70). this makes 100% change to 140, minus 70 so it starts in the right spot. Assuming you plan of applying this to your existing watchface, I might suggest adding a center point or two for realism.
Sorry for managing to miss your reply. In the creator you can add a centerpoint that covers the very center of the watch. Purely an aesthetic suggestion, nothing functional.
