Trellis Visualizations

Trellised visualizations enable you to quickly recognize similarities or differences between different categories in the data. Each individual panel in a trellis visualization displays a subset of the original data table, where the subsets are defined by the categories available in a column or hierarchy.

For example, if you choose to trellis a visualization based on the two variables "Gender" and "Political affiliation", this will result in four separate panels representing the combinations Female-Republican, Female-Democrat, Male-Republican, and Male-Democrat. If the "Gender" variable is used in conjunction with another variable that has five different values, this will yield ten panels. From this follows that variables with a continuous distribution and a wide range of values (for example, Real values) should be binned before they are used to form a trellis visualization. Otherwise the number of panels quickly becomes unmanageable.  


This is a standard non-trellised scatter plot:


By trellising this visualization based on Gender and Political affiliation, it will look like this:


  1. Select the visualization you want to trellis.

  2. Right-click on the visualization and select Properties.

  3. Select Trellis.

  4. Select the Rows and Columns you want to trellis by.

  5. Specify additional trellis parameters, and click Close.
