AlwaysUseFullForXYScatterPlots

This read-write property determines whether Full or Delta mode retrieval is forced for all tags in a scatter plot regardless of the retrieval settings that are configured at the application or tag level.

Syntax

aaHistClientTrend.AlwaysUseFullForXYScatterPlots = discrete;

Result = aaHistClientTrend.AlwaysUseFullForXYScatterPlots;

Remarks

If this property is set to True, then full or delta retrieval is forced. Full retrieval is used when retrieving data from an AVEVA Historian with a version of 9.0 or higher. Delta retrieval is used for earlier server versions.

The default value is True. We recommend to keep this option enabled unless the nature of your data makes full retrieval impractical.
