How do I view only some of the results at once?

To view results by item category, use the Categories section. Click to select one category only. Shift+click to select multiple categories to view results by. The Categories filter is not shown if there is only one category.

Similarly, the results can be viewed by participant group using the Groups filter. The functionality is the same as with categories.

To view the results by item, you can either select the item from the drop-down menu or click the item circle in the plot. Shift+click to select multiple items.

Additionally, you can create item tags and tag items with them. Once there are tagged items you can filter the results by tag.
