Type: function(holdToken)

Fired when a session is initialized. This is either when:

  • a new session is started, e.g. when chart.startNewSession() is called, or when the user clicks on the "start over" button on the "session expired" dialog
  • or when the chart is (re-)rendered with an already active session, e.g. after a browser refresh.

The holdToken parameter that gets passed into this callback is an object with the following structure:

"token": "wvXbB9MlHt",
"expiresAt": "2020-01-06T10:58:44.715Z",
"expiresInSeconds": 599
