This section describes the Mosaic tab that is associated with a mosaic plot. To access the mosaic plot properties, right-click near the center of a plot, and select from the pop-up menu.
The Mosaic tab controls attributes of the mosaic plot. The Mosaic tab is shown in Figure 6.5.
The Mosaic tab contains the following UI controls:
- “Other” threshold (%)
-
sets a cutoff value for determining which observations are placed into an “Others” category.
- Layout
-
sets the method by which cells are formed from the X and Y variables.
- 2 way
-
In this layout scheme, the X variables determine groups, and the mosaic plot displays a stacked bar chart of the Y variable for each group.
- N way
-
This layout scheme is available only if there are exactly two X variables. In this layout scheme, the plot subdivides in the horizontal direction by the first X variable, then subdivides in the vertical direction by the Y variable, and finally subdivides in the horizontal direction by the second X variable.
- Show labels for all tiles
