"Style" Tab: Used to configure the font style for label objects (text) in the current Ranged Label Thematic Map.

  • Segmentation Expression: This combo box sets the thematic variable for the Ranged Label Thematic Map. The property field used for segmentation must be numeric. Label objects corresponding to features within the same value range will share identical text styles, while those in different ranges will display distinct text styles.
    • The dropdown list displays numeric property fields from vector datasets eligible for creating Ranged Label Thematic Maps. Users may select any field to modify the current thematic variable or input an existing field name. Choosing "Expression..." from the dropdown opens the "SQL Expression" dialog for constructing mathematical expressions with property fields.
    • After building the field expression, click the "Refresh" button beside the combo box. The current Ranged Label Thematic Map will re-segment label objects (text) using the new thematic variable and update display effects.
  • Graduated Method: The right-side combo box specifies the segmentation approach for thematic values. The dropdown lists all available graduated methods provided by the application.
