先前的研究表明，多色尺度上级有序亮度尺度，用于支持复杂可视化的识别任务（分类，绝对数值判断等），而有序的亮度标度对于相对比较任务（更大/更小）是优越的上级。我们研究了执行这些任务的过程。通过研究眼动和比较不同大小的尺度上的表现，我们认为：（a）人们通过对图例进行连续的视觉搜索来执行识别任务，其速度对尺度颜色的数量和颜色的可辨别性敏感;（B）人们使用不同的过程来执行相对比较任务。对于多色尺度，他们执行图例的并行搜索，其速度对尺度的大小相对不敏感，而对于亮度尺度，人们通常直接比较可视化中的目标颜色，而很少参考图例。性能的比较是相对稳健的规模大小的增加，而性能的鉴定显着恶化，特别是亮度尺度，一旦规模大小达到10种颜色或更多。
Previous research has shown that multicolored scales are superior to ordered brightness scales for supporting identification tasks on complex visualizations (categorization, absolute numeric value judgments, etc.), whereas ordered brightness scales are superior for relative comparison tasks (greater/less). We examined the processes by which such tasks are performed. By studying eye movements and by comparing performance on scales of different sizes, we argued that (a) people perform identification tasks by conducting a serial visual search of the legend, whose speed is sensitive to the number of scale colors and the discriminability of the colors; and (b) people perform relative comparison tasks using different processes for multicolored versus brightness scales. With multicolored scales, they perform a parallel search of the legend, whose speed is relatively insensitive to the size of the scale, whereas with brightness scales, people usually directly compare the target colors in the visualization, while making little reference to the legend. Performance of comparisons was relatively robust against increases in scale size, whereas performance of identifications deteriorated markedly, especially with brightness scales, once scale sizes reached 10 colors or more.
