Analyze Exa Data in Infragistics Reveal

Reveal is a data visualization solution provided by Infragistics and can be paired with the CData API Server to build dynamic dashboards from live Exa data. The CData API Server generates an OData API for Exa, which is natively consumable in Reveal. In this article, we walk through connecting to Exa in API Server and connecting to the API Server from Infragistics Reveal to create a simple dashboard.

Connect to Exa from API Server

CData API Server uses a straightforward, point-and-click interface to connect to data sources and generate APIs.

1. Open API Server and click Settings -> Connection -> Add Connection
2. Select "Exa"
3. Enter the necessary authentication properties to connect to Exa.

   Start by setting the Profile connection property to the location of the Exa Profile on disk (e.g. C:\profiles\Exa.apip). Next, set the ProfileSettings connection property to the connection string for Exa (see below).

   Exa API Profile Settings

   Visit dashboard.exa.ai, sign in or create an account, and generate an API key from your API settings.

   

Add Exa Resource Definitions in API Server

After connecting to Exa, create Resources, which represent API endpoints for Exa data.

1. Click Settings -> Resources -> Add Resource
2. Select the Exa connection
3. Select the table you wish to retrieve and click Next
4. (Optional) Edit the resource to select specific fields and more
5. Save the settings

Add an API Server User

Create a User to connect to Exa from Reveal through API Server.

1. Click Settings -> Users
2. Click Add
3. Configure a User with access to the Exa Connection and Resource(s)

(Optional) Configure Cross-Origin Resource Sharing (CORS)

When accessing and connecting to multiple different domains from an application such as Ajax, there is a possibility of violating the limitations of cross-site scripting. In that case, configure the CORS settings in Settings -> Server.

• Enable cross-origin resource sharing (CORS): ON
• Allow all domains without '*': ON
• Access-Control-Allow-Methods: GET, PUT, POST, OPTIONS
• Access-Control-Allow-Headers: Authorization

Save the changes to the settings.

Create a Dashboard in Reveal

With the API Server configured, we can visualize Exa data in Reveal.

1. Log into Reveal and click Dashboards -> New
2. Click Data Source -> OData Feed
3. Specify the API Server API endpoint URL, for example: https://serverurl/api.rsc
4. Select Generic Credentials and specify the API Server username and authentication token
5. Select the entity you wish to visualize
6. Select fields and choose a chart type
