Hello,

I have this code for making animated plots in a loop and writing it into a video. However, when my second loop runs, the second plot appears to be plotted on top of the previous first plot.

filename='audioShockRecall.xlsx';
sheetname_kinovea=regexprep(filename,'.xlsx','');
conditioning=3;
col='B':'D';
x=1:1:509;
y1=10;
curve=animatedline('LineWidth',2,'Color','b');
set(gca, 'ylim',[0 500], 'xlim',[0 510],'OuterPosition',[0 0 1 1]);
grid on;
ylabel('\fontsize{14}Speed,px/s');
xlabel('\fontsize{14}Time,frame');
for i=1:conditioning
    speed=xlsread(filename,sheetname_kinovea,strcat(col(i),':',col(i)));
    figure(i);
    for j=1:length(speed)
        addpoints(curve,x(j),speed(j));
        drawnow
        F(j)=getframe(gcf);
        title(strcat('Trajectory:Conditioning',(num2str(i))),'FontSize',16);
    end
    video=VideoWriter(strcat('Conditioning',num2str(i),'.mp4'),'MPEG-4');
    video.FrameRate=30;
    open(video);
    writeVideo(video,F);
    close(video);
end

How can I plot them all in separate figure? Or is there something wrong I wrote.

Yes, that's what you told it to do. You first plotted an animated line in figure 1, then in your loop you said

figure(i);

so it reused figure #1 on the first iteration of your for loop. You should have just said

figure

and let it decide for itself what the number is.

And you forgot to attach 'audioShockRecall.xlsx' so we could run it.

For someone who ever needs it, I fixed the code as this way.

filename='audioShockRecall.xlsx';
sheetname_kinovea=regexprep(filename,'.xlsx','');
conditioning=3;
col='B':'D';
ylabel('\fontsize{14}Speed,px/s');
xlabel('\fontsize{14}Time,frame');
x=1:1:509;
for i=1:conditioning
    clear y
    y=xlsread(filename,sheetname_kinovea,strcat(col(i),':',col(i))); 
    figure(i);
    set(gca, 'ylim',[0 500], 'xlim',[0 510],'OuterPosition',[0 0 1 1]);
    curve=animatedline('LineWidth',2,'Color','b');
    grid on;
    for j=1:length(y)
        addpoints(curve,x(j),y(j));
        drawnow
        F(j)=getframe(gcf);
        title(strcat('Trajectory:Conditioning',(num2str(i))),'FontSize',16);
    end
    video=VideoWriter(strcat('Conditioning',num2str(i),'.mp4'),'MPEG-4');
    video.FrameRate=29.97;
    open(video);
    writeVideo(video,F);
    close(video);
    close all
end
