The key insight is that start/end parameters affect the **width calculation**, not just the binning boundaries. + +**Algorithm:** +1. **Calculate effective range**: Only expand, never shrink the data range + - ``effective_min = MIN(start, data_min)`` if start specified + - ``effective_max = MAX(end, data_max)`` if end specified + - ``effective_range = effective_max - effective_min`` + +2. **Apply magnitude-based width calculation** with boundary handling: + - If ``effective_range`` is exactly a power of 10: ``width = 10^(FLOOR(LOG10(effective_range)) - 1)`` + - Otherwise: ``width =
