-HDRHistogram Packet Latency
-===========================
+Packet Latency
+==============
 
-Latency results are generated from a single execution of NDRPDR discovery
-test across physical testbeds hosted LF FD.io labs: 3n-hsw, 2n-skx, 3n-
-skx, 3n-tsh, 2n-clx.
+VPP latency results are generated based on the test data obtained from
+|csit-release| NDR-PDR throughput tests executed across physical
+testbeds hosted in LF FD.io labs: 3n-skx, 2n-skx, 2n-clx, 3n-tsh, 2n-tx2,
+2n-zn2, 2n-aws, 3n-aws.
+
+Latency by percentile distribution plots are used to show packet latency
+percentiles at different packet rate load levels: i) No-Load latency
+streams only, ii) Low-Load at 10% PDR, iii) Mid-Load at 50% PDR and iv)
+High-Load at 90% PDR.
+
+For more details, see :ref:`latency_methodology`.
+
+Additional information about graph data:
+
+#. **Graph Title**: describes tested DUT packet path.
+
+#. **X-axis Labels**: percentile of packets.
+
+#. **Y-axis Labels**: measured one-way packet latency values in [uSec].
+
+#. **Graph Legend**: list of latency tests at different packet rate load
+   level.
+
+#. **Hover Information**: packet rate load level, stream direction
+   (East-West, West-East), percentile, one-way latency.
