Small multiples are a popular method of summarizing and comparing multiple
facets of complex data sets. Since they typically do not take into account
correlations between items, serial inspection is needed to search and compare
items, which can be ineffective. To address this, we introduce
CorrelatedMultiples, an alternative of small multiples in which items are
placed so that distances reflect dissimilarities. We propose a constrained
multidimensional scaling (CMDS) solver that preserves spatial proximity while
forcing items to fit within a fixed region. We evaluate the effectiveness of
CorrelatedMultiples through a controlled user study, and compare the CMDS
method with competing methods. We also demonstrate the usefulness of
CorrelatedMultiples in a case study on visual analysis of stock market
trends.
