startAngle seems

[mohamed-montaser1]

How do I make the animation start at the top of the circle??

Set your animationStartValue to 1 and your
startAngle: -Math.PI/2
This should set it to the top. I haven't used this for 3 years so I'm going by memory.

You can calculate the angle with this. Just enter the degree in this formula.

Math.PI * ((degree / 360) * 2 - 0.5)

0 ° will start from the top.
