catoffset
Attach vectors function.
Syntax
catoffset(mode, expr_1, expr_2, ...,expr_n
Argument
- mode
 - 
                            
- 0
 - Attach x vectors only.
 - 1
 - Attach x and y vectors.
 
 - expr_1, expr_2, ...,expr_n
 - Two or more valid vector expressions.
 
Example
Source curves 1 and 2, as shown below. Curve 1 and curve 2 have four points each.

Comments
catoffset appends a flexible number of curves based on attaching x vectors only or attaching x and y vectors.
