Analyze Google Calendar Data in Infragistics Reveal

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

Connect to Google Calendar 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 "Google Calendar"
3. Enter the necessary authentication properties to connect to Google Calendar.

   You can connect to Google APIs on behalf of individual users or on behalf of a domain. Google uses the OAuth authentication standard. See the "Getting Started" section of the help documentation for a guide.

   

Add Google Calendar Resource Definitions in API Server

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

1. Click Settings -> Resources -> Add Resource
2. Select the Google Calendar 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 Google Calendar from Reveal through API Server.

1. Click Settings -> Users
2. Click Add
3. Configure a User with access to the Google Calendar 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 Google Calendar 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
