I have a sub VI thats continuously reads data from a PCIe-6363. In the main vi i have successfully displayed the data in a waveform graph that is continuously updated with a control reference and property node. however I need to access the data being displayed in the graph, do some analysis and manipulation then display the data in a second graph. Everything I have tried to get the data that the main graph is being fed results in the new data display (graph) not updating until exection is stopped. then as soon as execution is restarted the new graph shows the last data graph and does nothing until main is stoped an started again.
what am i doing wrong?
