Flipping the axis starting value of a plot in matlab

Hi,

Here is the code that I wrote for plotting some points and writing it to a video. When I want to match the plot with the original video the origin value of y axis of my created plot is reversed. How can I change to y axis origin?

clear all;clc;
clear X; clear Y;

filename='test';
Ezfilename=strcat(filename,'_LocationOutput.csv');
col='I':'J';
repeats=1;

X=xlsread(Ezfilename,regexprep(Ezfilename,'.csv',''),strcat(col(1),':',col(1)));
Y=xlsread(Ezfilename,regexprep(Ezfilename,'.csv',''),strcat(col(2),':',col(2)));
for i=1:repeats
    writerObj=VideoWriter(strcat('Conditioning',num2str(i),'.mp4'),'MPEG-4');
    writerObj.FrameRate=30;
    open(writerObj);
    
    figure(i);
    dscatter(X,Y);
    colorbar;
    hold on
    plot1=scatter(X(1),Y(1),100,'r+');
    grid on;
    box on;
    xlabel('[px]')
    ylabel('[px]')
    xlim([0 1280]);
    ylim([0 720]);
    title('Animal movement during conditioning');
    for j=1:length(X)
        plot1.XData=X(j);
        plot1.YData=Y(j);
        %addpoints(curve(X(j),Y(j)));
        drawnow
        F(j)=getframe(gcf);
        writeVideo(writerObj,F(j));
    end
    close(writerObj);
    close all
end

Please give your recommendations,

Thank you

Does this do what you want

figure(i);
dscatter(X,Y);
colorbar;
hold on
set(gca,'YDir','reverse') % <- added this line

Oh, nice. This is exactly what i was trying to say. Thanks!
