TimeOffset - property of the tvPoints object
The time of each point from 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).
Property access for read and write
The default value is 0.
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.
var oTView = pMe.Items("../TrendView");
var oPoints = oTView.Trends("t1").Points;
var tNow = Pm.Time;
var vTimes = Pm.CreatePmArray().Array1(tNow-6/24, tNow-5/24, tNow-4/24, tNow-3/24, tNow-2/24, tNow-1/24);
var vValues = Pm.CreatePmArray().Array1(60, 40, 70, 50, 10, 80);
oTView.TimeSetType = 1;
oPoints.AddPoints(vTimes, vValues, 0, 0);
//Moving the whole curve into the current time minus one day.
oPoints.TimeOffset = tNow - 1;
