How are graduated symbols used in classification schemes?
Graduated symbols are used to show a quantitative difference between mapped features by varying the size of symbols. Data is classified into ranges that are each then assigned a symbol size to represent the range. For instance, if your classification scheme has four classes, four different symbol sizes are assigned.
When do you create a graduated symbols map?
A graduated symbols map is also created when you perform spatial aggregation. Click the Flip card button to turn the map card over. The back of the card includes statistics and a text box for a description of the map.
When to use normalization in graduated symbology?
Normalization is available only when the graduated symbology is based on a field. If it is symbolized on an expression, the Normalization field is unavailable. Classify the data using an appropriate classification method and number of classes. Set the minimum and maximum sizes of the symbol representing your data.
How do I get graduated symbols to get bigger?
If you want your graduated symbols to get larger when you zoom in, set a reference scale. Right-click the data frame and click Set Reference Scale. Your symbols will scale as the map’s page size is scaled. See Working with data frame reference scales for more information.
Where do I find graduated symbols in ArcGIS Pro?
Select a feature layer in the Contents pane. On the Appearance tab, in the Drawing group, click Symbology and click Graduated Symbols. The Symbology pane appears. In the Symbology pane, on the Primary symbology tab , choose the numeric field for the data to be mapped, or write an expression.
How to use graduated symbols in a layer?
A key design aspect in using graduated symbols for a layer is about classifying numerical data. See Classifying numerical fields for graduated symbology for a good overview on the classification methods available in ArcGIS. Right-click the layer in the table of contents and click Properties .
