My use case for Ping Plotter pretty much never includes opening the time graph to such a big scale, so until recently this functionality never occured to me. In the last few months, though, we've had several requests for it, so it's possible we may be able to fit this in to a future version. I've got an enhancement request logged for it, but no guarantees on if/when you'll see it.

Thanks for the feedback, suggestion, and great image!
