The Split feature allows you to add a third dimension to a table and a chart in order to see data patterns and how they compare.
Split by pane
Drag&drop the variables you want to represent the third dimension in a special pane called Split By in the DeX space.
You can add both single-variable options and multiple options from different variables;
You can add them separately ‘as list’ or combine them all together with OR-join function;
The creation of new options is also available after some variables are added to the Splits. You can make them on the fly by dragging new options to the panel and using logical operations from the pop-up menu. Also, you can open the split's menu, click on the logical expression builder icon and create logical variables.
You can activate/deactivate options by clicking on them on the pane or using the ‘eye’ icons in the menu;
You can delete options one at a time or all of them at once.
Even though the Splits are added in the crosstab mode, only two dimensions are available at a time in DeX. Here we can create the relevant variable, check to see if it works, then it's best to switch to the chart mode and visualize all three dimensions. You can read how to do that in this article.
