 Packet Throughput Graphs
 ========================
 
+Plotted results are generated by multiple executions of the same CSIT
+performance tests across three physical testbeds within LF FD.io labs.
+To provide a descriptive summary view, Box-and-Whisker plots are used to
+display variation in measured throughput values, without making any
+assumptions of the underlying statistical distribution.
+
+For each plotted test case, Box-and-Whisker plots show the quartiles
+(Min, 1st quartile / 25th percentile, 2nd quartile / 50th percentile /
+mean, 3rd quartile / 75th percentile, Max) across collected data set
+(data set size stated in the note below). Outliers are plotted as
+individual points. Min and max values are plotted as bottom and top
+Whiskers respectively. 2nd and 3rd quartiles are plotted as bottom and
+top edge of the box. If multiple samples match only two values, and all
+samples fall between them, then no whiskers are plotted. If all samples
+have the same value, only a horizontal line is plotted.
+
+*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 vpp performance jobs`_ jobs that created result output
+files used as data sources for the graph, *Y-axis labels* are measured Packets
+Per Second [pps] values, and the *Graph legend* lists the plotted test suites
+and their indices.
+
+
+.. note::
+
+    Test results have been generated by
+    `FD.io test executor vpp performance jobs`_ with Robot Framework result
+    files csit-vpp-perf-\*.zip `archived here <../../_static/archive/>`_.
+    Plotted data set size per test case is equal to the number of job executions
+    presented in this report version: **10**.
