Scaling a line horizontally on scroll

Hi there, I’m trying to animate a line (on a fixed position) horizontally when scrolling down. The more the user scroll, the more the line gets longer. I thought I could achieve this with the scale animation tool but unfortunately it’s only getting bigger on both with and height, there seems to have no option for non-proportional scaling. (And no anchor point as well) That’s so odd… Anyone can help with this? Thanks!

Hi! You can position a line beyond the edge of the editor and animate it on scroll to move across the screen. Fix it on screen under Position in your widget controls to keep it on the page while scrolling.
