Control and Update Infographic with Sliders in After Effects

Learn how to create an adjustable pie chart infographic, where you can control and update all the information using sliders.

In Part I, we will be building the infographic itself.

The Expressions Used in Part 1

The below expression is used on the Transition Completion on the Radial Wipe effect, on the first circle “1”

slider = thisComp.layer("CONTROLS").effect(name)("Slider");
100 - slider;

The below expression is used on the Start Angle on the Radial Wipe effect, on the second circle “2”

TC = thisComp.layer(index+1).effect("Radial Wipe")("Transition Completion");
A = thisComp.layer(index+1).effect("Radial Wipe")("Start Angle");
(100-TC) * 3.6 + A;

The Expressions Used in Part 2

The below expression is used on the Rotation of “Null 01”

T = thisComp.layer("1").effect("Radial Wipe")("Transition Completion")
A = thisComp.layer("1").effect("Radial Wipe")("Start Angle");
R1 = A * -3.6;
R2 = (R1+360) / 2 + A;

The below expression is used on the Rotation of your number to counter the rotation of the chart and keep it upright at all times

r = thisComp.layer("null 01").transform.rotation;
-r

The below expression is added to ‘Source Text’ of each number used

n = thisComp.layer("PIE CONTROLS").effect(name)("Slider");
Math.round(n)
