Creating a trellised visualization

A visualization that is trellised is split into a number of panels, where each panel represents a subset of the data. Using trellised visualizations, you can spot similarities and differences between the subsets of data, or within the subsets.

The subsets can be defined by splitting the data into categories that are available in a data column, alternatively by splitting it per data column, and then each category or column is displayed in a panel of its own.

For splitting data per data columns, see Visualizations trellised by data columns.

For example, the image below shows temperature data that is gathered for the different seasons during a three-year period. The maximum temperature per year is displayed in a bar chart.
Trellis introduction.
Assume you want to compare the highest temperature per season category across the years. By trellising the visualization by season you can view the seasonal temperatures in different panels.

The panels above are placed horizontally, but you can also place them vertically, or evenly distributed in a matrix.

Note: Table visualizations, cross tables, and summary tables cannot be trellised.

Prerequisites

A visualization that is not in a table format is created.

Procedure

  • In the data panel, select the column with the categories by which you want to split the visualization, and drag and drop it on any of the trellis drop targets.

    The visualization splits into panels.
    Tip: In the Properties popover for the visualization, the Trellis section, more trellis options are available.
