I have done some experimenting, and I think I'm on to something. If you create a graph from the put menu, then right-click and select Open; and then Put an array on the opened subpatch, you can see the red outline where you can decide what will be graphed-on the parent graph. It would not be too hard to send editmode and mouse movement messages to that canvas to move arrays around inside it; and it probably would actually be more efficient than copying. But I also notice that the graph subpatch has, in its options, an x and y margin, which moves the red outline. IF it's possible to change these values with messages, it could be trivial to move that red outline to cover several well-placed arrays, meaning that the graph would indeed switch arrays like you want. I started to look at the Pd code to see if I can find such a message mentioned; if I find it I'll let you know. -Chuckk > Chuckk Hubbard wrote: > > It would be possible, if not CPU-efficient, to have them all hidden in > > table objects, and simply use tabread and tabwrite to copy them to the > > skeleton array when you want to switch.
