Hello, I want to create a video showing 3 separate plots progressing forward as an animation. Now, the data (x1, y1, x2, y2, x3, y3) is obtained from experimental results and not aperiodic equation. How do I do this?

I understand that you want to create an animation of three data sets being plotted over time. The code you provided performs the basic plotting that you need. Creating two additional 'animatedline' objects will allow you to plot the separate data. Then, you need to capture each snapshot and save them all to a video. After the 'drawnow' command in your 'for' loop, include this line of code
F(k1) = getframe(gcf);
This will save each frame to a structure named 'F'. After the 'for' loop, include the following code to create and save the frames to a video file:
video = VideoWriter('video.avi');
open(video);
writeVideo(video,F);
close(video);
For more information on the 'VideoWriter' object, refer to:
