Selections

Selections are user interactions which show specific subsets of data, both in the intersection size bars and in the element view plots.

Selection Types​

There are 3 types of selections: Intersection, Graphical, and Explicit. Only one selection type is active at a time, though inactive selections still affect specific areas of the plot.

Selection Chips​

At the top of the element view, a series of selection chips show the current bookmarks and selections. The active selection takes a darker background than the rest of the chips. Any number of bookmark chips may be shown, with no limit on the number of bookmarks defined in the plot. Only one unbookmarked selected intersection may be shown. Similarly, only the single graphical selection and explicit selection will be shown; these cannot be duplicated or bookmarked.

Selection Chips

Clicking any chip will toggle its status as the active selection. The bookmark icon on the chips representing intersections can be used to toggle their bookmark status. These chips disappear as soon as the corresponding intersection is no longer selected or bookmarked. Chips representing graphical and explicit selections cannot be removed by interacting with them; these are only deleted when the selection is cleared via its corresponding interface.

Selection Size Bars​

Whether graphical, explicit, or intersectional, the active selection appears in the size bars of all intersections that contain elements which match the selection parameters. Graphical and explicit selections show a partial size bar representing the number of elements in the intersection matching these parameters, colored blue (for explicit) or orange (for graphical):

If the advanced scale is active, these selection size bars wrap into the nested bars:

The selected intersection & bookmarks have their size bars filled in with their bookmark color if the active selection is an intersection:

Selection Ticks​

All selections, regardless of their active state, are displayed on the size bars with colored ticks; the active selection has a tick (matching the selection color) at the end of its partial (or full, for intersectional) size bar. Since these ticks persist, they allow size comparisons between different selection types on an intersection-by-intersection basis.

An active explicit selection with ticks for intersection & graphical selections

The example above shows an active explicit selection with an inactive graphical selection and 2 bookmarked intersections. The graphical selection is smaller than the explicit selection in all size bars, indicated by the orange graphical ticks left of the blue explicit ticks. The two bookmarked intersections have 3 ticks, with the third tick matching their bookmark color.

If a selection matches no elements in an intersection, the tick for that selection does not appear in the size bar:

An active explicit selection that does not match two intersections with an inactive graphical selection

In this example, the 4th and 6th intersections have no elements matching the explicit selection, but all have elements matching the graphical selection.
