Graphics

Point, polyline, and polygon geometries displayed using graphics and a graphics layer

What is a graphic?

A graphic is a visual element displayed on a map or scene. A graphic is used to temporarily display features as points, lines, and polygons on a map or scene. For example, you can use a graphic to display a marker with your current GPS location.

You can use graphics to:

  • Display points, lines, polygons, and text in a map or scene.
  • Display geometry with different symbols in 2D and 3D.
  • Move elements on the display.
  • Display attributes in a pop-up when an element is clicked.

How a graphic works

Graphics are used to display a point, line, polygon, or text on a map or scene. They are temporary and are created at runtime by an application. For example, you can use data from a GPS to display a graphic on a map that represents the location of a device. The graphic (and data) do not persist when the application closes.

Graphics can be added to a graphics layer, graphic overlay, or view. To ensure they are always visible, they are typically added on top of all other layers. When a map view displays a map, graphics are the last to be displayed.

Graphic composition

A graphic is composed of a geometry, symbol, and attributes.

Geometry

A graphic contains a geometry which defines its position on earth. A geometry is a geometric shape such as a point, polyline, or polygon.

      }
    }
  ]
};

Symbol

A graphic contains a symbol that defines how it is displayed. A symbol contains styling information. Simple symbols have one layer and are displayed as vectors. More complex symbols can be composed of multiple layers. Marker symbols can display an image at the location of a point geometry.

To display a graphic in 2D or 3D, in most cases you can use a 2D symbol.

To display a graphic with a 3D shape, use a 3D symbol.

Attributes

Graphics can also contain attributes. Attributes are field and data values that describe the graphic. For example, a graphic can contain name, ID, and type attributes. Attributes are useful for displaying information when a user clicks on a graphic.

Examples

Display graphics in a map

This example displays a point, line, and polygon in a map. It adds graphics to a graphics layer or an overlay. It also adds a simple pop-up when the graphic is clicked.

Steps

  1. Create a geometry to define the coordinates and shape.
  2. Create a symbol to define the style.
  3. Define attributes to show data when they are clicked.
  4. Add the graphic to a graphics layer, graphics overlay, or view.

Display graphics in a scene

This example displays a point, line, and polygon in a scene. It adds graphics to a graphic layer or an overlay.

Steps

  1. Create a geometry to define the coordinates and shape.
  2. Create a symbol to define the style.
  3. Define attributes to show data when they are clicked.
  4. Add the graphic to a graphic layer, graphic overlay, or view.
