ValuesVisible - property of object tvGraph

Description:
Visibility of trend data points value.
Syntax:
ValuesVisible As Boolean
Calling:
oGraph.ValuesVisible = b
Note:
Property access for read and write. The preset value of this property is defined in the "Graphic mode > Visible values" configurator of this object.

When the object is created, the value of this property is copied from the TrendsView.GraphInit object.

 
Values are drawn if the property is set to true. At the same time the current length of the time axis (the difference between TrendsView.TimeMax and TrendsView.TimeMin properties) must be less than the value of the TrendsView.TimeZoomMaxForPoints property.
Example:
Setting the visibility of the point values to the particular tvGraph objects. Values of the points are displayed only when the current length of the time axis is less than the value of the TrendsView.TimeZoomMaxForValues property, i.e. 1min30sec.
Dim oGraph, oTrend
Set oTrend = oTView.Trends("t1")
oTView.TimeZoomMaxForValues = "1min30sec"
Set oGraph = oTrend.AddGraph(1, 0, "LimitVal(gt;100)")
If Not oGraph Is Nothing Then
  oGraph.ValuesVisible = true
End If
