Re: Animating percentage bars in a chart

I would set the anchor point of the bars to the right edge and add a Slider Control to each bar layer. Then I'd use a scale expression like this:

w = effect("Slider Control")("Slider");
[w,100]

For the corresponding text layer, I'd use a position expression like this (assumes the layer is positioned properly in y):

margin = 10;
L = thisComp.layer("bar 1");
x = L.transform.position[0] - L.width*L.transform.scale[0]/100;
[x+margin,value[1]]

And a Source Text expression like this:

s = thisComp.layer("bar 1").effect("Slider Control")("Slider");
Math.round(s) + "%"
