For the interactive Capability Plot, it'd be great to show Expected % Out of Spec also. The Expected PPM may be useful for some, but for most people this is a value that needs re-calculation back to a real world metric, i.e. percentage.
In the next release, Expected % and Expected Count have been added to the Interactive Capability Plot report, and the outline has been renamed "Nonconformance". The Expected Count is hidden by default.
