I am currently trying to solve a problem with several trends on an important display.
The trends in question display forcasted data from "t-1h" to "t+24h" alongside historical data for the same time period:
However, the trend does not update automatically, forcing users to refresh the display using one of the toolbars.
I have experimented with using the script below to refresh the trend but it doesn't have any effect on the trends:
Private Sub RevertTrends()
Dim sym As Symbol
For Each sym In ThisDisplay.Symbols
If sym.Name = pbSymbolTrend1 Then
sym.SetTimeRange Trend1.ConfigStartTime, Trend1.ConfigEndTime
ElseIf sym.Name = pbSymbolTrend2 Then
sym.SetTimeRange Trend2.ConfigStartTime, Trend2.ConfigEndTime
Please can someone help me come up with a way to force the display to update its contents every 5 seconds. Many thanks in advance.
For trends to show continuously updating data, the end time must use the syntax " *+N" where N is an increment of time in the future, such as 15 minutes, 1 hour or 1 day.
