在分析数据时，比较是一项常见的任务。在可视化中，比较任务自然是基于数据的可视化表示来执行的。直观的比较使我们能够深入了解单纯的数值差异计算无法掌握数据中复杂的相互依赖性的地方。然而，视觉上的比较也是有代价的。在解释视觉表现和交互进行比较时都有成本。我们提出了一些技术来减少与视觉比较相关的一些成本。我们解决了在视觉表现中比较对象的认知成本，以及在比较对象之间选择和导航的交互成本。我们的技术是通过比较地形图中的地理区域的例子来说明的。
Comparison is a frequent task when analyzing data. In visualization, comparison tasks are naturally carried out based on a visual representation of the data. Visual comparison allows us to gain insight where plain computations of numerical differences alone cannot grasp the complex interdependencies in the data. Yet, visual comparison also comes at a cost. There are costs when interpreting the visual representation and costs when interactively carrying out the comparison. We present techniques to reduce some of the costs associated with visual comparison. We address cognitive costs for comparing objects that are spread across a visual representation and interaction costs for selecting and navigating between objects to be compared. Our techniques are illustrated by the example of comparing geographic regions in choropleth maps.
