Meaning of Visual Graph with Venkman Profiler HTML output

Hello:

I think I've read all of the various links and articles on the Venkman
profiler, but can't find a meaningful explanation for the graph that
appears in the HTML output.

>From what I can infer, it is showing the min, max and average
total-time values for a specific method.

What doesn't make sense is how those images relate to the larger
graph-body. I would expect that it shows those min, max and average
times in relation to the total time. However, doing the math (reading
the HTML sizes of the various images), it doesn't seem to match.

A better graph might be to show the total time in relation to the
overall page time. Or show the min, max, average times inside a larger
graph body that is sized to the overall page cost.

If anyone has more information on what this graph represents, please
pass it along!

Regards,
Glenn
