Identify or Overlay Events on an SQC Chart

I have SQC charts in ProcessBook (version, and I would like to overlay event context within the chart itself.  I would prefer to place a vertical line at the point where a certain event occurs.  This event is unrelated to the SQC alarming trigger tags but will help the users understand why an alarm occured.  I could add information to the PB display outside of the control chart, but it not efficient for users browsing through hundreds of data points.  For example, when monitoring a piece of equipment, I would like to see when a maintenance event occured so that I can view alarms in context of that maintenance event.


I cannot seem to find a way to add other lines or points to an SQC chart.  Has anyone ever done the following programmatically?

  1. added a vertical line to an SQC chart
  2. changed the shape and/or color of a single point on an SQC chart, triggered by an event/tag that is not on the SQC chart


Here is an example of what I want to do:
