The graduated style component simulates a map session layer by visualizing the distribution of attribute values across classes. It implies that all of the values in the selected column are divided into classes, and each class is given a color. This style is a powerful tool for visualizing aspects such as the distribution or density of a given attribute across an area of interest.

The components of the graduated styling are -

  1. Zoom Extent - This component determines the zoom limits to which map session layer can be extended.
    Note: The session layer does not display if the zoom level is less than the minimum or greater than the maximum value of the zoom extent.
  2. Attribute - This component specifies the attribute required to create the Classes and Distribution Range that are based on the values of this column in the database.
  3. Method - This component determines how the range for the classes in the distribution are classified. Given a range and a maximum class limit, the different methods for classification are given below:
    • Equal Interval - Divides the range into equal intervals including the lower limit and excluding the upper limit.
    • Quantile - This method creates classes that contain an equal number of data values.
    • Natural Breaks (Jenks) - A data clustering method that produces an optimized distribution of classes by reducing the variance within classes and maximizing the variance between classes.
    • Standard Deviation -This groups the classes based on the standard deviation of the values from the mean.
    • Pretty Breaks - This method implements classes based on rounded numbers like 100, 1000 for example
    • Custom - By default, the custom ranges implement equal intervals where you can modify the limits to create your own custom range.
  4. Classes - Selects the maximum number of classes that can be produced from the class distribution range.
  5. Color - You can select the extreme colors to represent the minimum and maximum value from the selected attribute. The colors corresponding to the class distribution in the session layer are chosen from this scale.
  6. Label Feature - Labels can be added into the session layer by switching the toggle option on and selecting the attribute to be used as a label. For more information on this, see Fixed Styling.
  7. Icon & Text Styles - There are two components in this section - Fill and Labels.
    • Fill - You can modify icon styling options such as fill Width, Fill Opacity, Border Opacity and Border for the selected layer.
    • Labels - You can modify text styling options such as Color, Font, Spacing, and Transform for the selected layer.
  8. Classes - A list of all the output of the class distribution is displayed depending on the method selected, along with the assigned color for that range. You can also delete or modify the values for the range.
  9. Set Default - This option is reserved for records that don't contain the attribute that determines the distribution. These parameters cannot be edited.

The applied changes after graduated styling are represented on the map session layer.
