[Imported] delete trend historic data - deleting using ST or vbscript

Hi,
Trend historic data value for a point can be deleted manually from delete dialog box which appears on right-clicking trend.
I am looking to automate this feature. Main purpose is to load historic values for a point from a file.[csv] [ there are examples how to do it in help] and delete historical data on demand and reload with another set of values when instrument is calibrated.

Is there a way to do it using ST or vbscript to delete HISTORICAL Data for a point on runtime. Point considered is an internal analog point.

thanks,

Not yet. There will be a Method call in the next release!

You can use a 3rd party OPC HDA client.
