plot(1:10,1:10,'s')

Can I set MarkerFaceColor to red for point 1,2,3 while leave the other points unchanged?

I tried in interactive figure editor, it seems this is impossible.

Yes!

figure
plot(1:10, 1:10, 's')
hold on
plot((1:3), (1:3), 'sr','MarkerFaceColor','r')
hold off

As always, my (our) pleasure!

Ah, on desktop changing the MarkerHandle.FaceColorData to a 4 x N uint8 array gives a warning about wrong data. If you change it to a 4 x 1 uint8 array, then it does affect what is drawn.

MATLAB Online did not give me the warning message, but ignored the 4 x N data anyhow.
