Hi
I have an animated plot, and I want to save it - possibly an animation, and I want to know how to do it?

%% Make some data
t = 1:0.1:2*pi
y = sin(t)
%% Initialize video
myVideo = VideoWriter('myVideoFile'); %open video file
myVideo.FrameRate = 10; %can adjust this, 5 - 10 works well for me
open(myVideo)
%% Plot in a loop and grab frames
for i=1:1:length(t)
plot(t(1:i), y(1:i), 'LineWidth', 3)
ylim([-1, 1])
xlim([0, 2*pi])
pause(0.01) %Pause and grab frame
frame = getframe(gcf); %get frame
writeVideo(myVideo, frame);
end
close(myVideo)

Hi everyone!
Can I ask you a favour as it may be similar to the previous one?
I am trying to copy/transfer a plot (figure) in psychtool box window.
Do you know how I can do that?
I have my plot:
AccuracyFinal=[accuracy1,accuracy2,accuracy3,accuracy4,accuracy5];
plot(AccuracyFinal,'b--','LineWidth',5);
title('The Test Trend')
xlabel('Exercise')
ylabel('Accuracy')
legend('Trend','Location','northeast')
xlim ([1 5])
xticks([1 2 3 4 5])
ylim ([0 100])
yticks([10 20 30 40 50 60 70 80 90 100])
This is how I transfered it to psychtool box window with this code:
set(gcf, 'Position', [0 0 250 250]);
saveas(gcf, 'img.jpg');
myImage=imread("img.jpg");
tex=Screen('MakeTexture',win, myImage);
Screen('DrawTexture', win,tex)
The problem is that the name of axes do not appear and neither the title or the legend!
Please let me knwo if you can help me out!!
Thank you!

I'm not sure why, but could you simply re-add the axes titles, title, and such once you replot it?
