Hi! How can I get the right figure without reversing the direction of the two axes?
p.s. The figure on the right is created by me and there may be errors on the real (y) coordinates of the matrix.
data = importdata("data.txt");
figure
plot(data(:,2), data(:,1), 'b.', 'MarkerSize', 10);
axis equal
xlim([0 512]);
ylim([0 512]);

Ran in:
Try something like this —
data = readmatrix('https://www.mathworks.com/matlabcentral/answers/uploaded_files/1236147/data.txt');
figure
plot(data(:,2), data(:,1), 'b.', 'MarkerSize', 10);
axis equal
xlim([0 512]);
ylim([0 512]);
yt = yticks;
yticklabels(flip(yt))
.
