Polyline slow

    Polyline is too much slow to draw an array of data with about one
    thousand of points and it is fast to draw a second array of data with
    the same dimension of the first one. The only difference in the two
    arrays is that the first graph is less linear than the second but the
    time to elaborate it is about ten times than the second. Ten times!!??
    Is it possible? How can I make it faster

    Did you actually have a question about C++?
