Description
Default, BufferedDisplay is True.

Charts are drawn to an "internal" canvas and then it is shown on screen. This prevents "flickering" and, when charts have a lot of points, can gain speed as it's faster to show an entire chart than drawing all points directly to screen.

For realtime charts, where new points are continuously being added, this is a must.
