In this present case, I could see the bound info being calculated via a callback that fetches the 'quantized position property for the Y values, but the X values would still need to be calculated by consulting the normal stems à la lines 559-570. Were I to place the calculation in a callback, it would require a code dup of these lines. To avoid this, I could create a property called x-positions and change the name of positions to y-positions and quantized positions to quantized-y-positions. Then, I'd put lines 559-570 in a separate callback for the X positions. Lemme know if this sounds good.
