Yay, animating live activity data works. 

Nice hack: MPAndroidChart supports animating values, but only animating
a new entry, going from zero to its actual value. We want to animate
a single entry changing its value.

Since it's just a single entry, we can let a custom animator do this
(without knowledge of any other entries).
