Small multiple
open-in-new
<p>A small multiple (sometimes called trellis chart, lattice chart, grid chart, or panel chart) is a series of similar <a href="/facts/Infographic/yGbFkPUp">graphs</a> or <a href="/facts/Chart/2xshvBX0">charts</a> using the same scale and axes, allowing them to be easily compared. It uses multiple views to show different partitions of a <a href="/facts/Dataset/eDvegUTK">dataset</a>. The term was popularized by <a href="/facts/Edward_Tufte/t5jYFE2X">Edward Tufte</a>. </p><p>According to Tufte, </p> <blockquote><p>At the heart of quantitative reasoning is a single question: <i>Compared to what?</i> Small multiple designs, multivariate and data bountiful, answer directly by visually enforcing comparisons of changes, of the differences among objects, of the scope of alternatives. For a wide range of problems in data presentation, small multiples are the best design solution.</p></blockquote>
