这项研究旨在确定三种趋势格式中哪一种在要求受试者做出复杂决策的任务中具有更好的性能。这项研究包括三种常用的格式：直线型、竖条型和水平条型。两个次要自变量是：时间点数量和缺失数据量。研究结果表明，应优先使用直线型图形，其次是垂直线型图形。第二个发现是，图形趋势显示上不相关的点和缺失的数据是操作员业绩下降的重要因素。
This study was designed to determine which of three types of trend formats results in superior performance for a task requiring the subject to make complex decisions. Three commonly used formats were included in the study: line type, vertical-bar type, and horizontal-bar type. Two secondary independent variables were: number of time points and amount of missing data. Results of the study indicate that preference should be given to line-type graphs, followed closely by the vertical-bar type. A secondary finding was that irrelevant points and missing data on graphic trend displays represent important factors in the degradation of operator performance.
