I am using Manim/Python to draw a clock face, then illustrate the idea of fractions of an hour. The minute hand sweeps from 12 to 3 o'clock (ie, 15 minutes) and as it draws, I want it to ink in as it goes, creating a wedge. I can't find out how to make it leave a trail. My usual source (ChatGPT) can't do it somehow (it keeps giving me failure after failure, drawing the clock face and the sweep of the minute hand, but not painting the arc as it goes).
