2、The figure of A is about twice as much that of B。
3、The income from sales is 10 million, making the company the highest one in sales。
4、The A’s income reaches 20 million, which is in the middle of the list。

The trend/ increase slowed down in May。

第三种情况：纵向、横向均有的说明。这种图标不仅要注意同一事物的变化趋势，也要注意不同事物之间的差距及变化。
