I know it's easy to use a rectangle with a duplicator to make a different style of visualizer in Cavalry, but I was hoping to use a single horizontal line as shown above rather than a series of vertical rectangles. But, for one, I can't figure out how to make the waveform only go in the positive vertical direction (it's bipolar by default), and two, I can't figure out how to make the line's 'fill' stay in one spot and simply expand upward as needed.
I explained that poorly but it should be obvious by looking at the gif what I'm talking about (hopefully). If anyone has any ideas about how to improve the visualizer, I'd appreciate it. Thanks.
