Sorry dear Mark
I didn't see the message when it was posted.
Google removed support for google charts/images as you can see in the link I attached, although my library still works. This is why I have not been able to add new functionalities since you have only developed the new types (gauge nothing more) to be used in web pages (javascript).
Obviously, it can be used with the webview as Antonio indicates, although when you have some time. Keep investigating.
The graphics of the previous version included some graphics that were not so pretty but just as functional to represent a gauge.
Greetings
