Description

• 

The NewestValues command returns a list of lists with the newest values of the references in reflist, preserving order.

• 

Each inner list will contain the numerical values of the newest values corresponding to that data set, or undefined if the data cannot be retrieved. The order of the values in the inner lists will match the order of the columns.

• 

This command tries to minimize the number of API calls required, and the amount of data retrieved.
