Possible use cases are:
For example, we have to execute graph B, only if another graph A finished without any error.
So there is a relation between these graphs.
We can achieve this behavior by creating a graph event listener.
We create a listener for
graph finished OK event of graph A
and choose an
execute graph task type with graph B specified for execution.
If we create another listener for graph B with the
execute graph task with graph C specified,
it will work as a chain of graphs.
Figure 32.2. The event source graph isn't specified, thus the listener works for all graphs in the specified sandbox
