You can refer to the following code snippet to solve the issue you are facing.
The code demonstrates a way to display data for every seconds (with a 2 second pause in the updation of the graph).
For future reference, the plots can be exported to individual frames (containing 2 second data plot) and subsequently to a GIF file as demonstrated in the code below.
close all;
% Create data for 10 seconds, 5 datas every 2 seconds.
data = 1:5:125; % 25 data points
time = 0.2:0.2:10;
% Generate the frames to be written to a GIF
for k = 1:5
if(k==1) % Only create plot for the first iteration, update subsequently
figure();
hold('on'); grid('on');
h = plot(time(1:5), data(1:5));
pause(2); % Comment/Delete this line if no pause of 2 seconds is required
legend('Animated graph, Updated every 2 Seconds');
xlabel('Time (seconds)');
ylabel('Data');
else
set(h, 'xdata',time(k+1:k+5));
set(h, 'ydata',data(k+1:k+5));
pause(2); % Comment/Delete this line if no pause of 2 seconds is required
end
title(['k = ' num2str(k)]);
% Save the frame as png with a resolution of 150 pixels per inch
print(['Frame ' num2str(k)], '-dpng', '-r150');
end
% To generate the animated gif
GifName = 'AnimatedGraph.GIF';
delay = 2; % Delay between frames (2 seconds)
for j = 1:5
[A, ~] = imread(['Frame ' num2str(j) '.png']);
[X, map] = rgb2ind(A, 256);
if j == 1
imwrite(X, map, GifName, 'gif', 'LoopCount', inf, 'DelayTime', delay)
else
imwrite(X, map, GifName, 'gif', 'WriteMode', 'append', 'DelayTime', delay)
end
end
