CP-1875 Two Dimensional Measurement Graph in SR has no concept for data values Status March 2019 Voting Packet Date of Last Update 2019/01/17 Person Assigned David Clunie Submitter Name Kevin ODonnell Submission Date 2018/11/09 Correction Number CP-1875 Log Summary: Two Dimensional Measurement Graph in SR has no concept for data values Name of Standard PS3.16 Rationale for Correction: TID 3990 Two Dimensional Measurement Graph row 4 CONTAINER says "no concept name". One alternative would be to use $MeasurementGraph like the other rows. The other alternative, proposed here, since we never say "no concept name", is to just leave it empty and add an explanation in the content item descriptions. It is permitted to have empty Concept Names for container content items that are not root content items.
