In most cases we would want to clear a graph to start with a new data acquisition. In my case, however, I would like to retain the previous cycle's values on the graph. The point of doing this being that I would like to see the state of transition between different cycles of acquisition. In this example different cycles of acquisition is analogous to executing one VI run.
The example here clears the graph every time I run the VI. Is there a way to set it to retain the graph from the previous run and explicitly clear only when the user wants to (which can be done using a property node and a Boolean control).
