Is it possible to set the 'MarkerFaceColor' of the x y plot accroding to y value? I want matlab automatically choose accroding to any scale for eg. lowerst value from blue to highest value to red.

No it is not possible with any documented method (maybe with undocumented methods).
The workaround is to not place markers in your plot() call, and instead
shape = 's';
hold on
scatter(x, y, pointsize, y, shape, 'filled')
hold off
If you want the edge color to be different than the face color then you will need to pass in options.
Note that most markers are drawn completely by edge and setting face color does not affect them.

x = linspace(0,3*pi,200);
y = cos(x) + rand(1,200);
sz = 25;
c = y/max(y)*10;
hold on;
