This node is a final outout node that chooses what values to ignore when creating a pivot analytic..
For example, if you'd like to not include any times where your system was powered down, you could collect a power-meter value to the Ignore node, that is true whenever the value is zero.
This node is used in only in pivot analytics.
Input #1 is a digital signal - when true, any data being fed into your Pivot Output nodes will simply be ignored.
