Autoscale

Autoscale in ProcessBook will only make the scale larger and not make the scale smaller.  To get around this one of our users did the following:

Private Sub Display_DataUpdate()
   ThisDisplay.Revert
End Sub

This would cause all of the trends to query the archive subsystem every 5 seconds.  There are also datasets on the display which cause us big headaches with pibasess using up a ton of CPU (this has been an issue for us since upgrading to 3.4.375.99 when some locking mechanism was changed to prevent pi database corruption).

 

Is there a way to make autoscale work in both directions?  It must be able to done with some code.
