The timeline in qualitative mode, showing three religious groups. A time range between 830 and 1090 is set as the filter.
{% endif %}

The Timeline shows the distribution of the different religious groups along the overall time period: 600–1400 CE. In confidence mode, the level of confidence is shown instead of religious groups (cf. the info texts of the {{ full_documentation_link('confidence', 'Confidence view') }} and of the {{ full_documentation_link('settings-pane', 'Settings pane') }}, respectively).

Content

The timeline consists of two graphs: the main timeline and a smaller overview. The graphs are described in the following.

Also, the view changes depending on the choice of show filtered data in the settings (cf. {{ full_documentation_link('settings-pane', 'documentation') }}): in all data mode, data that has been filtered out is indicated by less saturated colors. In only active mode, data that has been filtered out is hidden from the visualization in all views, including the timeline.

Main Timeline / Upper Graph

{% if show_figures %}
The timeline in qualitative mode.
{% endif %}

The main timeline shows either a qualitative summary or quantitative information, depending on the timeline mode selected in the settings pane. If quantitative is selected, the number of pieces of evidence of that type in that year is encoded into the height of the area as a stacked histogram. If qualitative is selected, the timeline only shows whether there is evidence of that type each year. The colors used in the graph match the ones used in the religion view or confidence view, depending on the display mode selected in the settings pane.

Importantly, the main timeline can be used to filter the data according to time (cf. {{ full_documentation_link('timeline-filtering', 'below', true) }}).

Overview / Lower Graph

The smaller overview serves as a minimap for the larger main timeline: it always shows the entire time range contained in the database.

By clicking and dragging in the overview, a rectangle can be drawn which represents a time range. The main timeline zooms to this time range and shows data in greater detail. The overview represented by the lower graph does not change during this zooming in the upper graph. Vice versa, if the data is filtered by clicking and dragging in the main timeline (cf. Filtering {{ full_documentation_link('timeline-filtering', 'below', true) }}), the selected range is indicated as a thick bar below the overview.

The rectangle representing the time range for zooming can be moved by clicking and dragging or altered by changing the width of the rectangle. Note the mouse cursor in form of a grabbing hand (or a four-headed arrow) when hovering over the rectangle or the double-headed arrow when hovering the left and right borders of the rectangle, respectively. Clicking anywhere in the overview outside the rectangle will deactivate the zooming.

Tooltips

When hovering over any of the graphs, a tooltip with a summary of pieces of evidence for that year is displayed. If the main timeline shows a smaller time range than the overview, the year in the tooltip depends on whether the mouse cursor is on the main timeline or the overview.

When selecting data in other views, through brushing and linking, only the selected data shows in the timeline. Note: Selecting data in the timeline itself is not possible.

Interaction

Filtering

By clicking and dragging in the main timeline, a rectangle can be drawn which represents a time range. Data outside the time range is filtered out; accordingly, the area outside the rectangle is displayed in less saturated colors. The time range serves as a time filter for the data across all views.

The rectangle representing the time range for filtering can be moved by clicking and dragging or altered by changing the width of the rectangle. Note the mouse cursor in form of a grabbing hand when hovering over the rectangle or the double-headed arrow when hovering the left and right borders of the rectangle, respectively. Clicking anywhere in the main timeline resets the filter.
