Use case

Customize the appearance of a point suitable for the data. For example, a point on the map styled with a circle could represent a drilled borehole location, whereas a cross could represent the location of an old coal mine shaft.

The sample loads with a predefined simple marker symbol, set as a red circle.

How it works

  1. Create a GraphicsOverlay and add a Graphic to it.
  2. The Graphic sets a Point geometry and a red circle SimpleMarkerSymbol.
