Hey Edwin,

We received your support ticket on this issue as well (and have responded to that), and it looks like your graph situation can be fixed by making an adjustment to your trace interval. If you should find yourself with any questions about this, please let us know.

As far as your question about how many switches your packets pass through - this is displayed in the upper portion (or "trace graph") in the program. PingPlotter is a trace route utility, and the trace graph portion of the program displays each device between you and your target and displays them as hops in your route. If you're interested, we cover this topic in quite a bit more detail here:

If you have any other questions - please let us know!

Best wishes,

-Gary
