GET api/v1/devices/{deviceId}/charts/{chartId}/measurements/channel/{channel}/field/{field}?startDate={startDate}&endDate={endDate}&limit={limit}&aggregationThreshold={aggregationThreshold}&rangeType={rangeType}

Get measurements for the specified device field. NB: This uses a different route to fit in better with the /devices/id/... format. If the device allows anonymous access this method will return the measurements without the need for authentication.
