QUESTION:
Is it possible to create an Auto-Style with "Curved Lines" option enabled?
Currently when creating a new graph Auto-Style with the "Curved Lines" option enabled and then applying the newly created Auto-Style to a new graph, the "Curved Lines" option won't be carried over to the new graph.

ANSWER:
This is working by design, any setting from the "Graph Options" menu won't be carried over using Auto-Styles.
