Limit Line Y List Data (Remote Command Only)
Defines a list of y values for a given limit line. Changing the number of elements in
the list, the limit line will be automatically turned off. Up to 200 points may be
defined for each limit using the following parameters.

Number of Limit Y List Points Query (Remote Query Only)
Returns the number of points in the limit y list. It should match the number of points
in the control, that is, the number of values for the x axis and for the corresponding y
axis must be identical. If one array is larger than the other, the limit trace is built
using only as much data as is contained in the smaller array.
An empty array returns the system error message “list is empty” to a data query, 0 to
a POINts query.
Remote Command
:CALCulate:DDEMod:LLINe[1]|2|…|6:Y:POINts?
Example
:CALC:DDEM:LLIN:Y:POIN?
Returns the number of y list points in the limit line 1
