在 MATLAB Online 中打开

There are several options:

x = 1:10;
y = rand(1,10);
subplot(3,1,1)
plot(x, y, '-ok')
title('Circles and Lines')
subplot(3,1,2)
plot(x, y, 'ok', 'MarkerFaceColor','k')
title('Filled Circles')
subplot(3,1,3)
plot(x, y, '.k')
title('Dots')

One of those (or a combination of them) should do what you want.

I guess plot(x, y, '-ok') this one is not working in while loop with hold on .

If you are plotting individual points in a loop, it is not possible to plot lines connecting them, since that is only possible when plotting two or more points. It is necessary to save the data as a vector, and then plot it after the loop completes.
