C.constructed with equal vertical distances corresponding to an equal percentage price change.
解释：
B is correct.
A linearly scaled (rather than a logarithmically scaled) chart is better suited for analysis of short-term price movements. A linear scale plots price against a vertical axis with an equal distance between prices, whereas with a logarithmic scale, equal vertical distances correspond to an equal percentage change. The difference between a logarithmic price chart and an arithmetic (linear) price chart can be small when analyzing a chart in the short term. However, major differences are apparent when analyzing longer-term charts (more than two years of price data).
麻烦 讲一下 linearly scaled 和 logarithmically scaled 谢谢。
