 At least one of the Y tag end times is indicated as the current time (by
using *) or is in the future (*+N) and is not synchronized or matched
with the X tag (if X is not updating).
If both the X tag and the Y tag are updating, an arrow indicator is shown in
each legend entry.
Updates for retrieval methods Recorded and Interpolated are received from
an event pipe that provides the application with snapshot values. For this
reason, when a tag is using recorded values, you may see many more
values while the plot is updating than are actually recorded. Once the plot
is regenerated or reverted, only recorded values are shown. When using the
interpolated retrieval method, values on the plot are interpolated using the
snapshots coming in through the event pipe.
Is an OLE Object in a Display Linked or
Embedded?
To determine if an object is linked or embedded, look at the border around
it. Linked objects are surrounded with dashed lines; embedded objects are
surrounded with solid lines.
Depending on the colors used, sometimes the border of an object is
difficult to see. If so, select the object and click the Edit menu. The last
entry in the menu appears as:
xx object for embedded objects
or
Linked xx object for linked objects
where xx is the object type such as document, spreadsheet, etc.
Linked Object Data Is Not Updating
If your linked data doesn't update when you open a display, click Edit >
Links.
