@@ -14,6 +14,25 @@ LF FD.io labs: 3n-hsw, 2n-skx, 2n-skx. Grouped bars illustrate the
 64B/78B packet throughput speedup ratio for 2- and 4-core multi-
 threaded VPP configurations relative to 1-core configurations.
 
+Additional information about graph data:
+
+#. **Graph Title**: describes tested packet path, testbed topology,
+   processor model, NIC model, packet size used by data plane workers and
+   indication of VPP DUT configuration.
+
+#. **X-axis Labels**: number of cores.
+
+#. **Y-axis Labels**: measured Packets Per Second [pps] throughput
+   values.
+
+#. **Graph Legend**: lists CSIT test suites executed to generate graphed test
+   results.
+
+#. **Hover Information**: lists number of runs executed, specific test
+   substring, mean value of the measured packet throughput, calculated perfect
+   throughput value, difference between measured and perfect values and
+   relative speedup value.
