Filter Explorer

Making the Filter Explorer permanently visible

The Filter Explorer is by default set up as a pop-up window meaning it is initially hidden but can be made visible through the click of a button. It hides when an indicator or date is selected or when the user clicks with the mouse outside of the component.

If you wish to make the Filter Explorer a permanently visible component, you should tick the check box for the property ‘Visible At Startup?’ and remove the tick for the properties ‘PopUp Window?’ and ‘Hide On Selection’.

Filter Type

In InstantAtlas dynamic reports, filters can be defined in one or more columns in the ‘Geography and Filters’ worksheet of the Excel Workbook (see Entering Filter Information). Each column forms a ‘filter group’. If you are using the Access Data Manager, filters groups are defined in the table ‘tblFilter’. Filter values for each filter group and how they are assigned to the geography features are set up in ‘tblFilterDetails’.

If the configuration property ‘Filter Type’ set to ‘single’, the end-user can only ever select one filter value at a time. When a second filter value is selected, the first filter value is deselected. This happens irrespective of whether the second filter value is of the same filter group or of a different filter group.

If the filter type is set to ‘combined’ then the end user can apply multiple filter values at the same time. This is done using the following rules:

Two or more selected values from the same filter group in the Filter Explorer are applied using an ‘OR’ rule. For example if the end user selects ‘Filter value A1’ and ‘Filter value A2’ within ‘Filter group A’ the map will be filtered to only show features that have either ‘Filter value A1’ OR ‘Filter value A2’ (or both) assigned to them.

Selecting two or more entries from different filter groups in the Filter Explorer causes an ‘AND’ rule to be applied. For example if the end user selects ‘Filter value A1’ within ‘Filter group A’ and ‘Filter value B1’ within ‘Filter group B’ the map will be filtered to only show features that have both ‘Filter value A1’ AND ‘Filter value B1’ assigned.

The ‘${filterValues}’ substitution variable (by default part of the map title) will contain a comma separated list of the applied filter values.
