Hi Christian, Thanks. The values are a series that need to be graphed. Some values in a series may be null, indicating that the graph line should be skipped at that point since we don’t know what the value is. That’s why I decided to use C_COLLECTION instead of ARRAY REAL to hold the values. As I build the graph, I need to know the min and max values in the series.
Yes, I can loop through the collection, of course. I just figured the collection probably had a function that would allow me to reduce the collection to non-nulls before applying .min() or .max() without having to loop. Trying to learn how to use all the collection functions. -- Cannon.Smith Synergy Farm Solutions Inc.
