Creating symbology based on multiple fields is required to assist in pattern analysis and data visualization. More than one field can be combined through the Change Style pane based on the list of attributes in the map. However, ArcGIS Online is unable to symbolize two text fields in the map viewer.
The image below is an attribute table showing the data on volcanic eruptions in Japan. Of the eight attributes, five are text fields (Name, Location, Type, Earthquake, Tsunami) and three are numeric fields (Year, Elevation, Volcanic Explosivity Index). The symbology based on Location and Type of volcano is to be created.
In the Change Style pane, choosing a text field as the first attribute causes the second attribute selection to display only the numeric fields.
Symbolizing two text fields is not supported in ArcGIS Online. Symbolizing options are limited to the following field types:
As a workaround, follow the steps below:
