Making treatment decisions based upon graphed data is important in helping professions. A small amount of research has compared usability between equal-interval and semi-log graphs, but no prior studies have compared different types of semi-log graphs. Using a randomized, cross-over, experimental design with 72 participants, this study examined the relative usability and acceptability of three types of graphs: Regular (equal-interval), Standard Celeration Chart (SCC; semi-log), and Standard Behavior Graph (SBG; semi-log). All participants used each graph across three usability tasks (Plotting Data, Writing Values, and Interpreting Trends). For the Plotting and Writing tasks, the equal-interval graph produced the greatest rate of correct responses. However, for the Interpreting task the SBG produced the greatest rate of corrects, while the equal-interval graph produced the smallest rate. User acceptability mainly favored the equal-interval and SBG graphs. Study findings and implications are discussed with respect to graph usability and acceptability during day-to-day practice.

根据图形数据做出治疗决策对于帮助专业很重要。少量研究比较了等间隔和半对数图的可用性，但没有先前的研究比较不同类型的半对数图。本研究使用包含 72 名参与者的随机、交叉、实验设计，检查了三种类型图表的相对可用性和可接受性：常规（等间隔）、标准加速图（SCC；半对数）和标准行为图（SBG；半对数）。所有参与者都在三个可用性任务（绘制数据、写入值和解释趋势）中使用了每个图表。对于绘图和写作任务，等间隔图产生的正确响应率最高。然而，对于口译任务，SBG 产生了最大的正确率，而等间隔图产生的速率最小。用户可接受性主要偏爱等间隔图和 SBG 图。在日常实践中讨论了关于图形可用性和可接受性的研究结果和影响。
