用英语描述线形图

用英语描述线形图 二、图形graphs: 1. 线形图line curve:折线图，曲线图或“时间序列图”( a time series graph )，它同两条轴线组成，每条轴线代表着一个变量。所以可以清楚地显示有发展关系的各变量之间在一段时间里的发展趋势，演示事物发展、变化的走向和趋势，便于读者对数据的结果或未来做一定的预测。线形图可分为简单线形图和多项线形图。前者只有一条线，而后者则有多条线。多项线形图应该被局限在三条或四条线上。 解读要点:1. 须注意整体阅读，观察走向和趋势;2. 须注意准确性和清晰度，因为线形图往往不能提供准确数据。 例图1:Labor Force Participation in Andrew’s High School Students' number350 319 300290282 200 150 100 50 0 Jan.Feb.Mar.Apr.MayJuneJuly 例图1:解读: The above figure visualizes labor force participation in Andrew’s High School over the period from January to July.
