From the developer:
This plug-in allows you to use one or more analog meters in your publication. You can customize each control with their own colors, face, general options, and events. Every analog gauge can be presented in three different styles: Left, Center, and Right. Each one allows you to play with many included properties that can be used in order to modify the gauges appearance and behavior.
You may want to check out more software, such as Events notification plugin, Smart Unfold For AutoCAD or Bumpgen, which might be similar to npGaug.
