When symbolizing point features using the Vary symbology by attribute functionality (by Color), if the point feature is published as a web layer, the colors do not display in the web map.

Workaround

• Instead of depicting the third field (GPMFlow) by color, within ArcGIS Online Map Viewer, click the Change Style button for the layer in question by navigating to Add attribute and specify the third field (GPMFlow).
• This represents the GPMFlow field by size, rather than by color.
