    ::解释圆形图

    A  circle graph  is a visual way of displaying data that is written in percents. The circle represents 100%. The circle is divided into sections. Each section shows what part of 100 that item represents. The circle graph uses different colors for each category being described. The legend on the right shows what each color corresponds to.

    This circle graph describes a student’s spending habits.Each color represents what his money is spent on. Blue is savings, red is baseball cards, and green is food. By looking at this graph, you may determine that this student saves half (or 50%) of all his money. He spends a smaller fraction on baseball cards and the rest on food.
    ::这个圆形图描述了学生的消费习惯。 每个颜色代表着他所花的钱。 蓝色代表储蓄,红色代表棒球卡,绿色代表食物。 通过查看这个图,您可以确定这位学生节约了一半(或50 % ) 。 他花在棒球卡上的钱少了一小部分,其余的则花在食物上。
