Trellis chart is a grid of small charts . It is sometimes called trellis chart, lattice chart, grid chart, or panel chart and is a series of similar graphs or charts using the same scale and axes, allowing them to be easily compared. It uses multiple views to show different partitions of a data set.
How does Trellis help?
- They allow for the display of many variables. The simplicity of the layout means end users are less confused. Stephen Few writes about over plotting where more than 3 variables are displayed. By using a chart such as Trellis, this problem can be avoided.
- Since all the charts use the same scale , end user can quickly learn to read an individual chart and apply this knowledge as they scan the rest of the charts. The end user is more focused on what the chart says vs how the chart works.
- Small multiples enable comparison across variables and reveal the range of potential patterns in the charts.
