QChart not rendering

  • hi
    i'm using Qchart and a timer for updating it, the timers works right , and the function working correctly, it says that the function is running 60 times per second but qchart just repaint(update) it self about 5 times per second.
    why qtchart not updating smoothly ? and just repaint it self about 5 times per second.

    Depending on how much data your application has to process, trying to refresh 60 times per second won't yield the effect you expect. Did you benchmark that part ?
