Example Filterable Data Maps
With filter controls, you can offer end users multiple views of data in a single visualization. (Note that one or more filter controls are required if the source data for a visualization has duplicate data.)
The WCMS offers several settings for filter controls. You can control the sort order for each filter’s selection list. You can include a reset option. And you can select the type of control for each filter: dropdown, tab, pill button, or tab bar.
The first example below is a map with multiple dropdown filters and a reset control. The second example has a single filter with tab controls and no reset option.
Remember to test the usability of filterable visualizations, particularly when mixing control types. We recommend that you consult with your organization’s accessibility officer.
Pre-filtering is another option for maps with filters. For more see Data Map.
