有效的字形可视化设计涉及到许多不同的视觉编码。由于空间位置通常已经预先指定，因此我们必须依赖其他视觉通道来传达多变量分析的其他关系。其中一种关系是数据中存在的表观顺序。本文提出了两个众包的实证研究，专注于视觉通道，即Bertin的视网膜变量的有序性的感性评价。第一项研究探讨了不同视觉通道编码的元素序列中的顺序感知。我们发现的证据表明，某些视觉通道被认为是更有序的（例如，值），而其他视觉通道被认为是较不有序的（例如，色调）比数据中存在的测量顺序。因此，某些视觉通道对紊乱或多或少敏感。第二项研究评估视觉有序性如何影响序列中元素的最小和最大判断。我们发现，视觉通道往往被认为是有序的，提高了识别这些值的准确性。
The design of effective glyphs for visualisation involves a number of different visual encodings. Since spatial position is usually already specified in advance, we must rely on other visual channels to convey additional relationships for multivariate analysis. One such relationship is the apparent order present in the data. This paper presents two crowdsourcing empirical studies that focus on the perceptual evaluation of orderability for visual channels, namely Bertin's retinal variables. The first study investigates the perception of order in a sequence of elements encoded with different visual channels. We found evidence that certain visual channels are perceived as more ordered (for example, value) while others are perceived as less ordered (for example, hue) than the measured order present in the data. As a result, certain visual channels are more/less sensitive to disorder. The second study evaluates how visual orderability affects min and max judgements of elements in the sequence. We found that visual channels that tend to be perceived as ordered, improve the accuracy of identifying these values.
