How to overlay circles on google map using Flex 4

i'm trying to show affected areas on city.

I want to use semi transparent circles to show the intensity of the effect by altering the radius of the circle and animate it while placing them. for exa开发者_如何学Gomple it appears as a dot and then grows to the intended size in fraction of a sec.

I could see some functions in javascript API but not in Flex. Saw some examples that uses polygon. But i dont want to plot all 360 points for just one circle.

is there any way to achieve this?


To draw a circle you can use the FXG Ellipse primitive. Here's more info on drawing shapes: Adobe Flex 4 * Shapes

Hope that helps.


I used Sprites as marker icons and animated them on frame enter
