Marking items using the legend
You can mark items of a certain category using the legend in a visualization.
The legend displays settings made on various axes. An example of an axis is the Color axis, where each specified color represents a certain category. By clicking a category on an axis, you mark all items within that category.
For example, in the scatter plot below, the Color axis is used to mark all items in the "group d" category, that is, all yellow items. The other categories, "group a-c" and "group e", are grayed out in the legend to indicate that only the "group d" is marked.
