Same principle as 'Random' but allows you not only to select points to plot but also columns, and usually does a good job of fitting the resulting graph in the screen (the original project would go off the top the screen if you put in a large value for points). Also to increase speed of plotting there are 3 sprites all plotting points at once.
In turbo mode try: points=1000 columns=20 points=1000 columns=50 points=10000 columns=60 points=10000 columns=120 points=10000 columns=240 points=100000 columns=400
