hypertrending datatable objects

[INCO]

Is there any way that I can create a hypertrend trace for a member of a datatable? (i.e. how do I start logging datatable objects to the historical database?)

Inco,

To enable data members of the datatable object for logging, you simply open the data member configuration window, select the desired data member, and check the box that says "log to historical database." This is true for all Lookout objects.

here's the deal: I made a datatable so I can 'multiplex' various objects onto the same panel - on this panel I wish to have a hypertrend object that plots the member of the datatables (as indicated by the cursor)...

If you are mulitplexing several values to one display, you need to log all those values to the database, even if you are not currently displaying them. The hypertrend shows data from the historical database, so when you switch to another cell of the datatable, there must already be historical data logged.
