Creating a dynamic legend

Complejidad: Principiante Requisitos de datos: Instalado con el software Ruta de datos: C:\program Files\ArcGIS\Desktop10.0\TemplateData

The graphic table element can be used to create dynamic surround elements such as a legend. The dynamic legend is updated based on the data frame's visual extent whether the legend is used in an MPS-Atlas map series or within a single .mxd file.

Adding cartographic data

Before you can create the legend, you need to add the data to the map. In this walkthrough, you are using the USA dataset, which is in a template database that is included with the ArcGIS install.

Pasos:
  1. Click the Add Data button Agregar datos on the Standard toolbar.

    The Add Data dialog box appears.

  2. Browse to C:\Program Files\ArcGIS\Desktop10.0\Bin\TemplateData.
    NotaNota:

    The data used for this example is located at C:\Program Files\ArcGIS\Desktop10.0\Bin\TemplateData.gdb by default for a standard installation.

  3. Add all the feature classes within the USA feature dataset to the data frame except the states feature class.
  4. Once all the feature classes are added to ArcMap, organize the layers in the following order by clicking and dragging them to the appropriate location:
    • U.S. Cities
    • U.S. Rivers (Generalized)
    • Country boundary, international border and coastline, for the United States
    • U.S. National Transportation Atlas Interstate Highways
