TimeOffset - property of the tvPoints object

Description:

The time of each point in the buffer with points of the tvPoints object is increased by the value set in this property (either read from the trends server or 'manually' defined by the AddPoints method) and the trend progress is then drawn in these calculated time intervals (it is possible to move the whole curve on the time axis).

Syntax:

Double TimeOffset

Note:

Property access for read and write.

This property is also functional in Web panels.

The default value is 0.

Example:

The definition of the curve only by relative time intervals, displaying the curve in the real time is achieved by the offset definition in TimeOffset.
