BarChart animation

Hello, I'm working on a power graph using the Bar Chart. I have fixed the margins and I keep changing the values of the bars. I was wondering if there is any animation to move the bar from it's current position to the next value?

Start with the BarChart API and its existing animation entry points, then inspect how changing bar values is handled. Determine whether a value update can transition from the current bar position to the next value, and verify the resulting behavior with the chart example or relevant tests if available.
