Scrolling Dynamic Plot

[DKL1972]

Can someone give me some pointers on how to implement something like the data_plot example but where the screen width is scrollable so I can display a whole bunch of data as it fills up from right to left (I'm not doing left to right)? I am plotting real-time data as it comes in and it's probably going to end up being up to like 20,000 points. This also makes me wonder how I will shift the points in the array in an efficient manner since there are so many.

Thanks!
