Im controlling A helicopter with simulink and i would like a real time plotting of its position of its x and y cordinates on a GUI axes.
The x position and y position are two seperate signals. How can i get these two signals into and x,y graph that is continuously updated on to the GUI.
Thanks
p.s I have seperate signals of the euler angles and z position for the aircraft . How could i carry this on to have a 3d position of the aircraft.

Register an Event Listener to send the data to ghe GUI everytime the block output is updated:

Thanks Guy this looks like it will work
Im decided to use an XY scope so to put a listener on this i used
h = add_exec_event_listener(blk, event, listener)
Am i right in thinking that blk i can have as a variable i can change so it has different directory
Post Outputs will update the graph when it moves
And the Listener i have put to the handlles of my axes on the graph on my GUI ?

I am trying to understand your previous comment and I have no idea what this sentence means:
"Am i right in thinking that blk i can have as a variable i can change so it has different directory Post Outputs will update the graph when it moves"
Please add some punctuation or words to help us understand what you are looking for.
