Functional Details

This module stacks a series of n-dimensional fields to form a single (n+1)-dimensional field. You can also use Stack to add a dimension to a single field (e.g., "stack" it from 2 dimensions to 3 dimensions). Note that Stack does not accept partitioned data as input.

input

specifies the object(s) to be stacked. The field(s) must have regular connections. If the parameter specifies a series, the location of the stacked field in the new dimension is equal to the series position of that field. If the parameter specifies a group, then the location of each member of the group in the new dimension will be 0, 1, .... If the parameter specifies a field (rather than a field series), the n-dimensional data is converted to (n+1)-dimensional data, with the value of the extra dimension set to zero. A dimension can be specified by number (from 0 to n - 1). The first three can also be specified as x, y, and z, respectively. The default value is dimension 0 (zero).

Components

All input components are propagated to the output.
