Wheel momentum visualizer
Scroll inside the panel, then lift your fingers from the trackpad. The solid box follows active input; the translucent box also follows momentum after release. Both return to the center when their input ends. You can also drag the solid box. A mouse wheel may produce little or no momentum.
- Solid: user input
- Translucent: user input + momentum
Bars show each wheel event’s movement. Faded bars indicate detected momentum; the plot resets for each gesture.
