labels : {list,Array,Vector}, labels to use for data items in L

datatype : type, the data type for the DataSeries

The DataSeries constructor produces, from the input data L, a DataSeries data container with the data in L. If the labels = option is specified, then the data in the resulting DataSeries may be retrieved by using the labels specified, as well as by position, as for an Array or Vector . The input data (L) may be a list , a Vector , an Array , a table , or another DataSeries.

If the input L is a table , then the indices of L are used as the labels, while the entries of L are used as the data items. Note that, in this case, there is no pre-determined order for the data.

The input L may be an existing DataSeries, in which case you can use the constructor to produce a new DataSeries with a different (compatible) data type, or to re-label the data items.

The DataSeries command was introduced in Maple 2016.
