    Yep I meant > 100000

    Well normally I'm working with short audio signals and then the number
    of sample points is not a problem. The display is not updated dynamically.
    An audio signal is read and is shown in a window. That's it more or
    less. But when using large numbers of samples
    the problem described earlier arises. I'll try the max min idea, I had sort
    of come up with something similar in the mean time. Thanx for your comments.
    I just thought that since any data plotting utility will at some point be
    with more data points than a pc's resolution will be able to display as
    points solutions to this problem should be easy to find.
