Discrepancy between JMeter's Response Time in Summary Report and Response Times Over Time Graph

I hope that someone will help me to determine the reason of the discrepancy between the response time data in Summary Report and Response Times over Time.

Here's the data of the Summary Report:

enter image description here

.jtl (Summary Report) graph enter image description here

As you can see the Summary Report's average response time when clicking login is 2354 ms.

Here's the graph of Response Times over Time. enter image description here

enter image description here Here, the average response time when clicking login is 2723 ms.

Comparing the two graphs, the second graph (in pink) is missing a "16000ms" response time.

I don't see any "discrepancy" there, according to the documentation:

This graph will display for each sampler the average response time in milliseconds

Average response time is basically an arithmetic mean of indiviaual sampler's response times and the chart shows the response times over the test timeline with the given granularity

So looking into:

  1. Spike above 12 seconds
  2. Right part of the chart which is mostly below 2 seconds.

I would say that the chart is accurate. You can open your .jtl result file using LibreOffice Calc or equivalent and generate the same chart using Elapsed column - it should be the same.
