  Expression controls final keyframe value

  Posted by Deanna Keogh on August 19, 2021 at 6:49 am

  I’m building a graph template. I’m wanting to animate the y scale of the column shape layer, to which the y is already linked to an expression, which is subsequently linked to a slider. The slider controls the height of the shape/column and I would like to animate it so that no matter what value is placed in the slider, it still animates to the correct value. Basically I need to somehow have the slider value always be the value in last keyframe.

  Any ideas will be greatly appreciated

  My current y expression is as follows:

  x=100;
  y=(thisComp.layer("GRAPH CONTROLLER").effect("Graph")("Column 1"));
  [x,y]

  Many thanks 🙂

  Keyframe the animation like you would want it for a y-value of 100,

  then use this:

  x=100;
  y=(thisComp.layer("GRAPH CONTROLLER").effect("Graph")("Column 1")) * value[1]/100;
  [x,y];
