Hey John,

The vertical red bars that you see in the latency section of the summary graphs indicate each targets' average response time for the currently selected sample set. The scale for this is at the top of the latency graph (with the far left side reading
"0ms", and the right side being set with whatever your "high end" latency is).

It's *very* similar to the feature that's pointed out in the link you provided here (http://www.pingplotter.com/manual/theinterfacegraphs.html - point #7 specifically). The only difference is that on a summary screen, the value is on a target-by-target basis (so the line won't connect here the same way it does on the trace graphs).

We're actually in the process of doing some revision work to the product manual for an upcoming release, so we appreciate your feedback here! I'll be sure to get your notes forwarded on to our team so we can keep these things in mind as we move forward.

If you have any other questions, please let us know.

Best wishes,

-Gary
