If you want/need to measure the response bytes size from the jmeter results and analyze/get the trends. Following will help
Make sure you disable the flag “Keep-alive” in your HTTP request. (Found that enabling this can skew the payload size that jmeter reports. In a thread, if the request is made multiple times jmeter tool provides the cumulative payload size instead of the individual request response bytes. )
If you create CDF for this bytes data, the graph is a straight line with very high payload data which is ever increasing. Unless you need the keep-alive for your request, disable it in your http request.
