Constructor Details
Creates a new
Infographic dijit using the given DOM node.Parameters:
< |
Required | Various optional parameters that can be used to configure the dijit. All properties can be passed into the constructor as options. variables, type and studyArea are required when constructing an Infographic. |
< |
Required | Reference or id of an HTML element where the Infographic should be rendered. |
Sample:
var infographics = new esri.dijit.geoenrichment.Infographic({
studyArea: new esri.tasks.geoenrichment.GeometryStudyArea({
geometry: new esri.geometry.Point(-120.44,34.95)
}),
type: "AgePyramid",
variables: ["Age.*"]
}, "infographics");

Infographic. The default value is a RingBuffer with 1-mile radius.Default value:
new RingBuffer({"radii": [ 1 ], "units": "esriMiles"})Sample:

StringAn HTML template string used to define the Infographic subtitle. The default value is:
<div> ${address}</div><div>${name}</div>
If the study area is a point the address information is populated by performing a reverse geocode of the input study area. For other geometry types the value will be an empty string.
The name information is a string representation of the studyAreaOptions used by the infographic. For example "1-mile ring". (Added at v3.7)<String

Method Details
Define the infographic data. By default the Infographic uses online Geoenrichment services to obtain data. This method allows you to override this behavior to provide data from your own source. For example, you can use a FeatureSet returned from the GeoenrichmentTask.enrich method. (Added at v3.7)
Parameters:
< |
Required | Specify the FeatureSet containing the custom data to display in the Infographic. |
< |
Optional | Define the mappings of feature set attributes to Infographic display fields. Supported display fields are name and address. |
Finalizes the creation of this dijit. This method should be called after the constructor for this dijit is called and before letting the users interact with it.
Event Details
