loadingolapstructure

[starting from version: 2.3]

It is triggered for "microsoft analysis services" and "api" data source types:

For Microsoft Analysis Services, loadingolapstructure is triggered when the structure of an OLAP cube starts loading. Once the connection was established, the component begins loading the OLAP structure.
For the custom data source API, the event is triggered when the component sends the /fields request to the server.

To make sure that structure was loaded, use olapstructureloaded. To track any errors, use olapstructureerror.

Example

pivot.on('loadingolapstructure', function () {
  alert('Loading olap structure!');
});
