A ranges label thematic map refers to a label thematic map that annotates objects in the vector layer used to create the label thematic map based on a thematic variable (a property field or a mathematical expression of a field). The annotation content is the thematic value corresponding to the object.

At the same time, the label thematic map also divides all thematic values corresponding to objects in the vector layer used to create the map into multiple ranges based on another specified thematic variable (a property field or a mathematical expression of a field). Objects whose thematic values fall within the same range are displayed with one text style for their corresponding labels in the map, while objects in different ranges have different label text styles.

Therefore, the text styles of labels in a ranges label thematic map are not uniform but diverse, reflecting explanatory information for different categories of objects.
