Hi, I think you could just glue your new xy-coords onto the piddle of old ones and update the plot's dataset.
I guess it would be a lot faster to calculate all coords and then update the plot only once, but I don't know if that is feasible for your case. I am not sure if the change_dataset is available in the Simple module, though.
