Add a point, line, and polygon

Learn how to display point, line, and polygon graphics in a map.

You typically use graphics to display geographic data that is not connected to a database and that is not persisted, like highlighting a route between two locations, displaying a search buffer around a point, or tracking the location of a vehicle in real-time. Graphics are composed of a geometry, symbol, and attributes.

In this tutorial, you display points, lines, and polygons on a map as graphics.

To learn how to display data from data sources, see the Add a feature layer tutorial.

Prerequisites

Choose your API

You can do this tutorial in C++ or QML. Make your selection below:

• Steps for C++
• Steps for QML

Steps for C++

Open the project in Qt Creator

1. To start this tutorial, complete the Display a map tutorial or download and unzip the solution.

2. Open the display_a_map project in Qt Creator.

3. If you downloaded the Display a map solution, set your API key.

   More info

   An API Key enables access to services, web maps, and web scenes hosted in ArcGIS Online.

   1. Go to your developer dashboard to get your API key. For these tutorials, use your default API key. It is scoped to include all of the services demonstrated in the tutorials.

   2. In the Projects window, in the Sources folder, open the main.cpp file.

   3. Modify the code to set the API key. Paste the API key, acquired from your dashboard, between the quotes. Then save and close the file.

      main.cpp

Add GraphicsOverlay class, declare member function

GraphicsOverlay is a container for temporary graphics to display on your map view. The graphics drawn in graphics overlays are created at runtime and are not persisted when your application closes. Learn more about GraphicsOverlay.

1. In the display_a_map project, double click Headers > Display_a_map.h to open the file. Add the GraphicsOverlay class to the namespace ArcGISRuntime declaration.

Add a point graphic

A point graphic is created using a point and a marker symbol. A point is defined with x and y coordinates for longitude and latitude coordinates, and a spatial reference. The spatial reference is WGS84.

1. Create a Point and a SimpleMarkerSymbol. To create the Point, provide longitude (x) and latitude (y) coordinates, and a SpatialReference.

   More info

   Point graphics support a number of symbol types such as SimpleMarkerSymbol, PictureMarkerSymbol and TextSymbol. See Symbol in the API documentation to learn more about symbols.

Steps for QML

Open the project in Qt Creator

1. To start this tutorial, complete the Display a map tutorial or download and unzip the solution.

2. Open the display_a_map project in Qt Creator.

3. If you downloaded the Display a map solution, set your API key.

   More info

   An API Key enables access to services, web maps, and web scenes hosted in ArcGIS Online.

   1. Go to your developer dashboard to get your API key. For these tutorials, use your default API key. It is scoped to include all of the services demonstrated in the tutorials.

   2. In the Projects window, in the Sources folder, open the main.cpp file.

   3. Modify the code to set the API key. Paste the API key, acquired from your dashboard, between the quotes. Then save and close the file.

Add a GraphicsOverlay

GraphicsOverlay is a container for temporary graphics to display on your map view. The graphics drawn in graphics overlays are created at runtime and are not persisted when your application closes. Learn more about GraphicsOverlay.

1. If the main.qml file is not already open, in the Projects window, navigate to Resources > qml\qml.qrc > /qml and open main.qml.

2. Add the GraphicsOverlay type, giving it the id as shown.

Add point graphic

A Point defines a specific location, defined by an x,y coordinate pair, and a SpatialReference. Points represent discrete locations or entities, such as a geocoded house address, the location of a water meter in a water utility network, a moving vehicle, and so on. A point can also be used in a Viewpoint to define the center of the display, as in this tutorial app.

1. Add the following Point to identify Point Dume Beach.

   More info

   Point graphics support a number of symbol types such as SimpleMarkerSymbol, PictureMarkerSymbol and TextSymbol. See Symbol in the API documentation to learn more about symbols.

2. Create a SimpleMarkerSymbol symbol to display the point. Add the following code to create a small, round, red symbol. Also set the outline property to line_symbol, created in the next step.

   More info

   Symbols define how graphics and features appear on a map. Different symbols are used with different geometry types. A SimpleMarkerSymbol displays a predefined marker such as circle, cross, and so on. A simple marker symbol can also have an optional outline, defined by a SimpleLineSymbol, as in this tutorial.

   A SimpleLineSymbol is used to display a graphic or feature based on polyline geometries. Simple line symbols display predefined line style patterns, such as solid, dash, dot, and so on. Use a simple line symbol to add an outline to a marker symbol or polygon.

This Component.onCompleted code block could be added anywhere as long as it is a child of ApplicationWindow.

Add a polyline graphic

A connected sequence of points defines a polyline. Use a polyline and a line symbol to create a line graphic.

1. To create a polyline, add the following function to create a JSON object line1, with line segments and a spatial reference, and then call ArcGISRuntimeEnvironment.createObject to create the Qml object.

Add a polygon graphic

Create a polygon graphic using a polygon and a fill symbol. A connected sequence of points that describe a closed boundary defines a polygon.

1. A PolygonBuilder is a helper QML type used to create polygons. Use polygon_builder in a later step to connect a series of points and create the polygon. Add the following code to instantiate a PolygonBuilder.
