The tags view. Three tags were selected.
{% endif %}

This view shows tags which are associated with pieces of evidence (i.e., sets of data concerning a place, religious group, time span, and the respective confidences). Tags were implemented to include additional information and to make further distinctions possible. For instance, the tag Bishopric is attributed to pieces of evidence referring to bishoprics as distinguished from metropolitan sees. This way, the visualized data can be filtered according to additional criteria. Note that, by default, all tags are deselected. This means that no filters based on tags are active (cf. {{ full_documentation_link('tags-interaction', 'below', true) }}).

Contents

The view consists of a table, in which each row represents one tag. The rows are sorted by descending number of pieces of evidence. In what follows, the respective columns of one given row are described.

Checkboxes
The first column contains a checkbox used for filtering.
Tag Names
The second column shows the name of the tag. Generally, the name should be self-explanatory. Further information is displayed when hovering with the mouse.
Evidence Count Visualization
The third column visualizes the count of pieces of evidence for each source. The less saturated part of the bar represents pieces of evidence that are not active (i.e., do not match the current filters).

Interaction

Selection

Clicking on a row will select the tag, brush the represented data, and link related data in all views. For instance, locations in the map with pieces of evidence with the selected tag will be highlighted, other locations will be represented by less saturated colors. Clicking on the same row again will reset the selection. Selecting a different row, or an element in a different view, will replace the selection. Only one tag at a time can be selected.

Filtering

The visualized data can be filtered according to one tag or multiple tags in all views by (un-)checking the appropriate checkbox or checkboxes. Keep in mind that a piece of evidence can have no tag, one tag, or multiple tags. If, for instance, it has no tag, its visibility is not affected by the checkboxes. If, on the other hand, it has multiple tags, its visibility is only affected by (un-)checking all respective checkboxes. Note that the selection is not applied until the Apply button is clicked. Checking multiple (or all) tags works as a logical disjunction: a piece of evidence is matched if it is assigned any of the checked tags. The tag filter works together with filters from other views in logical conjunction: for instance, if only tag X and religion Y are selected in the respective views, only pieces of evidence with tag X and religion Y are matched.

Two additional buttons in the top left corner make filtering more convenient:

Clear all filters
Uncheck all checkboxes; that is, remove all filters based on tags. Note that this is not applied until the Apply button is clicked.
Revert checkboxes
Revert all checkboxes to represent the state of filters applied last.
