PingPlotter Pro has a built-in scripting engine which allows extensions to its capabilities.  There are a handful of default extensions that ship with PingPlotter Pro, and you can add more, or create your own.

The list of scripts that show in this dialog is controlled by the list of .ppx files the exist in your (PingPlotter Pro)\scripts directory.  By default, this path is:

c:\program files\PingPlotter Pro\scripts

Any .ppx file found in that directory will show up in this list.  The .ppx file itself controls if it defaults to be disabled or enabled.  Once it shows up on the list, you may need to manually enable (or disable it) through here.

You can completely disable the scripting engine, or just do any individual script.

To create a new script, just copy one of the existing ones from the script directory, and save it with a new name.  This script will then show up as a new one, and you can then edit it to do your bidding.
