Question

Creating a simple app that calculates the speed your going and displays it in a speedometer graphic. I can do all the speed calculations, gps calculations etc.. but i am not too sure about the animation. Does anyone have any good tutorials or examples on needle gauges other than the thermometer example out there?

Answer 1

You could probably start with something like this.

Then when transitioning between values, do an animation where the needle gradually moves to the next value X units per unit of time.

This question is also very similar to yours.
