Set signal to blank if condition is not present

[Brie Jones]

Is there a way to set a signal equal to blank if some condition is not active? I know how to do 0.splice($signal,$condition) to set it equal to 0 when the condition is not active, but I really want it to be blank and not zero during those times.

Hi Brie - You can try using the remove formula, i.e., $signal.remove($condition).  This should remove the data inside that condition.

It sounds like you want data when the condition is present, but no data when it isn't present. In that case, I would use

$signal.within($condition)
