The Tracking Point node creates a point along the path that your tracking hotspots can flow down in a line tracking analytic.
Input (Input #1) is linked to a destination node from another Tracking Point node.
Speed (Input #2) a number that describes the speed of the line at the point.
Size (Input #3) a number that is the length of the line between this node and the next one.
Active (Input #4) a true or false value that controls if the asset is available. This is used if you have a branch in your line (ie. one destination connected to two or more inputs) - the hotspot will flow to the next available node.
The active input is not used if there is only one destination node.
The len option is the length (in the same units as the speed) of the line between this node and the next.
The len option is only used if you haven't connected the size input. Size always overrides the length option.
The title of the node is the name of the piece of equipment that has been reached. The final hotspot will show the time at which it first reached this node.
