A Semi-Log (percent-of-change) price scale is a percentage-based scale. A 10% change in price will always be represented by the same displacement along the vertical axis, regardless of the absolute price change. A $5 price change from a $50 base price (10%) will be represented by the exact same vertical displacement as a $10 price change from a $100 base price (10%), even though the absolute values of $5 and $10 are not equal. | A Semi-Log (percent-of-change) price scale is a percentage-based scale.
