In the weekly meeting there's a bar chart: fraud loss rate was 2.0% last month and 2.2% this month, but the second bar looks twice as tall as the first, and the business team is panicking that fraud has doubled. You notice the y-axis starts at 1.8%. How would you walk them through what actually changed?

周会上有张柱状图，上个月欺诈损失率2.0%，这个月2.2%，但第二根柱子看起来比第一根高了一倍，业务方很紧张，说欺诈翻倍了。你一看发现纵轴是从1.8%开始画的。你会怎么跟他们解读这个变化？
