You can pre-fill arrays with empty values (-1e10) so they don't plot.

Hello,
Currenly all AFL arrays are setup so they have equal length (equal to number
of data points available for given symbol)
This is essential to enable them to match with price arrays.
This way given array element refers to the same date/time
as in other array. So 70th element of your custom array x[ 70 ]
refers to 70th bar of Close array and they both represent
value at given date.
If they were not one would never be sure if shorter array
refers to FIRST or LAST part of price array (or maybe some
part in the middle).
Best regards,
Tomasz Janeczko
