[Xymon] Question Regarding TCP Statistics Graph

Hello,

I'm a bit confused on what exactly this TCP Statistics graph is saying (image attached).

What exactly are the units in this graph?

The y axis shows ~1-2 events but the legend shows 100-600"m". What is the magnitude of "m" exactly?

Do the numbers in the legend not line up with the graph axis units? Is there a reason for this?

I would greatly appreciate if anyone could clear this up for me!

Thanks!!
