Filtering
For each aspect of confidence and each confidence level, a checkbox is shown in the respective cell. Unchecking a checkbox will filter out pieces of evidence with this confidence level for that aspect of confidence. This allows for a very fine-grained control over what data to visualize.
Note that the selection is not applied until the Apply button is clicked. This button is disabled if the selected filters are matching the data currently visualized.
The filters work in logical conjunction across different aspects of confidence; that is, having filters in place for multiple aspects of confidence will only show pieces of evidence that match all filters.
Four additional buttons in the top left corner make filtering more convenient:
- Uncheck all
- Uncheck all checkboxes.
- Invert
- Invert all checkboxes. Checked boxes are unchecked, unchecked boxes are checked.
- Check all
- Check all checkboxes.
- Default
- Revert the selection of checkboxes to the default. By default, all confidence levels are selected for confidence of location, and only certain and probable for the other confidence aspects.
In addition, entire rows or columns of checkboxes can be set to either checked or unchecked by clicking the row header (the confidence levels) or the column header (the aspects of confidence). Here, the new value for the new row (or column) is the inverse of what the majority of values (3 or more) was before; for example, if 4 checkboxes were checked and 2 unchecked for the uncertain row, clicking on the row header would uncheck all checkboxes in the row.
