Hi Daniel,
Thanks for writing in!
We've got an extension for PingPlotter Pro that sounds like it should accomplish what you're after. Have a look here for more details:

One important thing to make note of; PingPlotter is designed to measure *network* latency - and this extension measures *service* latency. If you're using this extension - it's usually a good practice to make sure you've got a few traces running to this target (one using the script, and one without) to make sure you're capturing all of the pertinent information.
Please let us know if you have any questions, or need any other assistance!
Best wishes,
-Gary
