PROBLEM
When attempting to change the style of a numeric field in ArcGIS Online Map Viewer Classic, the Counts and Amounts drawing style is not available, as shown in the image below.
Symbolizing attributes using the Counts and Amounts drawing style requires that the field type be numeric, either Double or Integer. ArcGIS Online recognizes a field type as numeric only when the field values are exclusively numeric characters. If the field values contain letters or special characters, the field is converted to String, a text data type representing a series of alphanumeric symbols and special characters.
For example, 32.8% contains a special character (%) and 45m contains a letter (m). ArcGIS Online reads the values as text.
Use one of the workarounds below to ensure field values are expressed in exclusively numeric characters and change the field type to Double or Integer.
In ArcGIS Online
Note: The option to change field values is only available for hosted feature layers. Refer to ArcGIS Online: Publish hosted feature layers for more information.
In Microsoft Excel
After the changes are made, the Counts and Amounts drawing style is available in ArcGIS Online Map Viewer Classic.
