## Instance Methods

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

Retrieves the next page of results.

### Method Details

`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 <code>me</code> to indicate
    the authenticated user. Only <code>me</code> 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
    <code>nextPageToken</code> from the previous response.
      x__xgafv: string, V1 error format.
        Allowed values
          1 - v1 error format
          2 - v2 error format

`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.
