Easy Tip: Save default themes
Raster If you repeatedly display a particular layer as a thematic map, it is possible to store the settings to build the theme within the table. This means that the thematic map is automatically displayed every time the table is opened.

For this example, we will use United Kingdom Output Area Boundaries. The thematic map is built from the 2011 UK Output Area boundaries published by the UK Office of National Statistics. The data includes population for which a density map has been created.

Save as Default Theme view 

When creating a Ranged or Individual Values thematic map, the option Save as Default Theme View is available in the Create Thematic Map – Step 3 of 3 dialog box.

Also, you do not have to choose this option when first creating the thematic map. The option is also available when modifying an existing thematic map.

Consider this can be a convenient way of sharing how data has been visualised. You do not need to package a workspace.

Additional info
  • The ability to saving a default thematic map is supported only for the Ranged and Individual Value types of thematic map.
  • Default themes are not applied when the table is opened as part of a workspace.
  • If needed, there is also an option to remove a default theme.
  • Only a single default theme is stored. If one is present and a new default theme is saved, it replaces the original. If you wish to have multiple default themes, consider if saving multiple copies of your table is a feasible option.
  • All the settings needed to rebuild the thematic map are stored in the TAB file.
