At my application, we have trends that shows the pressure at an HPU.  
I'm using the EasyChart to trend the pressure.  
I would like to do a second mark at the trend where I could calculate the deviation and show it automatically.

You should check out Phil's Note Chart Module:

It has this functionality built in.

While I believe it to be technically possible with the first party chart components, the task is far from trivial.

You could create any number of marks you want using value, range, and interval markers.
