Carr, Daniel B., Anthony R. Olsen, Jean-Yves P. Courbois, Suzanne Pierson, D. Andrew Carr. 1998. Linked micromap plots: named and described. Statistical Computing and Graphics Newsletter.9(1):24-31. NHEERL-COR-2277J

In this article we describe a new template for display of spatially indexed statistical summaries and give it a name: linked micromap plots (LM plots). Readers can obtain a general notion about the template from a quick glance at the three examples in this article. The LM template emerged from our environmental graphics research and has quickly jumped to other applications such as the display of federal statistics summaries. We foresee a wide range of applications that extend even to the study of gene communications networks. The template for LM plots has four key features. First, LM plots include at least three parallel sequences of panels that are linked by position. One sequence consists of micromaps, one sequence consists of linking legends, and one sequence consists of familiar statistical graphics, in this case times series panels. The template can include more sequences of panels as long as it has three types of panels. Sorting the units of study is the second feature. The third feature partitions the study units into panels to focus attention on a few units at a time. The fourth feature links representations for highlighted study units across corresponding panels of the sequences.
