`list(userId, dataSourceId, limit=None, pageToken=None, x__xgafv=None)`

    Queries for user's data point changes for a particular data source.

    Args:
      userId: string, List data points for the person identified. Use me to indicate the authenticated user. Only me is supported at this time. (required)
      dataSourceId: string, The data stream ID of the data source that created the dataset. (required)
      limit: integer, If specified, no more than this many data point changes will be included in the response.
      pageToken: string, The continuation token, which is used to page through large result sets. To get the next page of results, set this parameter to the value of nextPageToken from the previous response.
      x__xgafv: string, V1 error format.
        Allowed values
          1 - v1 error format
          2 - v2 error format

    Returns:
      An object of the form:

`list_next(previous_request, previous_response)`

    Retrieves the next page of results.

    Args:
      previous_request: The request for the previous page. (required)
      previous_response: The response from the request for the previous page. (required)

    Returns:
      A request object that you can call 'execute()' on to request the next
      page. Returns None if there are no more items in the collection.
