# Trellis Plot

A trellis plot (also known as a lattice plot or panel plot) is a group of smaller plots arranged in a grid. Each small plot represents a different condition or item, and all small plots share the same scales. Trellis plots make complex or high-dimensional data easier to interpret due to the common scales of small plots aligned in a grid, with each small plot containing a single difference compared to the others.

In the trellis plot shown above, the single difference between small plots is the subject (Unique Subject Identifier), (ALT) (blue) and BILI (red) can easily be contrasted both within and between subjects, over the time course of the study (Study Day of Specimen Collection).
