All the 3 bars have the anchor point set to the bottom and you can do that by pressing the Y key to select the anchor point and moving the anchor target to the bottom of the shape layer. In this example, we have 3 shape layers and we’re looking to animate the Y dimension using the wiggle expression. So let’s jump right into it and see how it’s done We’ll then add a slider for the amplitude so we can control the animation. We will use an expression to separate the x and y dimensions, something that we cannot achieve directly in the wiggle expression and apply the effect only to the y dimension. Wiggle is probably the most popular expression from After Effects, and in today’s article, we’ll take a look at an alternative way of using it to create an animation
