Hi Guys
I have written a real time plotter that plots 128 samples I receive from an EEG headset, one sample at the time and attached is the result.
Obviously, since I'm plotting one point at a time, it is not going to be continuous enough.

Is there anyway to do real time interpolation to some how connect these dots?
If not, how do people produce real time plots that are continuous (smooth or jagged doesn't matter)?

To produce a line that appears continuous, change your plots to:
plot(i+Seconds*128,Channel_1,'-r','LineWidth',1.8)
plot(i+Seconds*128,Channel_2,'-g','LineWidth',1.8)
The '--' linetype will plot a dashed line, the '-' linetype will plot a continuous one.
