 Packet Latency Graphs
 =====================
 
+Plotted results are generated from a single execution of CSIT NDR discovery
+test. Box plots are used to show the Minimum, Median and Maximum packet
+latency per test.
+
+*Title of each graph* is a regex (regular expression) matching all
+throughput test cases plotted on this graph, *X-axis labels* are indices
+of individual test suites executed by
+`FD.io test executor dpdk performance jobs`_ that created result output file
+used as data source for the graph, *Y-axis labels* are measured packet Latency
+[uSec] values, and the *Graph legend* lists the plotted test suites and their
+indices. Latency is reported for concurrent symmetric bi-directional flows,
+separately for each direction: i) West-to-East:
+TGint1-to-SUT1-to-SUT2-to-TGint2, and ii) East-to-West:
+TGint2-to-SUT2-to-SUT1-to-TGint1.
+
+.. note::
+
+    Test results have been generated by
+    `FD.io test executor dpdk performance jobs`_ with Robot Framework result
+    files csit-dpdk-perf-\*.zip `archived here <../../_static/archive/>`_.
