When unfiltered, the graph at the head of the search results presents a bar graph of the number of transactions relative to date. Toward the top-left of the graph, it indicates that no filters have been applied.
When a single filter is applied, such as the Score filter, that is indicated at the top-left of the graph and the search results are displayed using that filter.
As more filters are applied, they are indicated at the top-left of the graph and the number of search results displayed becomes more narrow.
You can also click and drag across the graph to filter your results by the selected date range.
