Hi All -
I'm working with a "scatter" type plot (QwtPlotCurve without the curve) to display data contained in a large circular buffer (200k points updating at around 2k-5k points per second). Adding points to the plot at this rate is no problem - I'm using the DirectPainter and everything is running fine. What I would like to do is remove the points from the plot as they get overwritten in the circular buffer. Is there a trick to this that I haven't found, or does this imply re-plotting the whole buffer? What about something simple like overwriting the next block of points with white-colored points?
Thanks much,
Joe.
