Thematic layers always display directly above their main layer in the Layer list for the map that is shown in the Explorer window. To distinguish the thematic layers from the main layer, the thematic layer is indented.
Thematic layers always stay with their main layer. Dragging a main layer will automatically drag its thematic layer with it, even if it is not selected. When selecting a main layer and a thematic layer that was created from a different main layer, the thematic layer's main layer must also be selected to reorder it. For instance, Layer Main1 has two thematic layers, Theme1a and Theme1b. Layer Main2 has one thematic layer, Theme2a. If Layer Main1 and Theme2a are selected for reordering, Layer Main2 must also be selected.
You can move the main (base) layer without moving the grid theme; once the grid is created it is separate from the main layer.
Dragging a thematic, however, will only drag itself. Thematic layers that are based on the same main layer can be reordered among themselves, according to the draw order ranking. Theme layers can only be inserted amongst other theme layers that are of the same draw order ranking. Draw order ranking is determined as follows:
- Pie and Bar charts and Graduated Symbol thematic layers hold the highest draw order ranking. They will always be the top thematic layer.
- Dot Density holds the next draw order ranking. These themes will always fall below Pie and Bar charts and Graduated Symbol themes.
- Ranged and Individual Value thematic layers hold the lowest draw order ranking. They will always be below Pie and Bar charts, Graduated Symbol, and Dot Density thematic layers.
