Each dataset can have its own custom styling, editable on the web within the dataset map view. Point, Line and Polygon, fill and outline colors, as well as transparency levels can be customized, and custom symbology graphics can be uploaded for point data.
Tap "Show Styling Options" to set the fill color and outline color of geometries, and upload symbols for points.
Colors can be changed and opacity levels set. As soon as changes are saved, all mobile and web clients are updated.
