transparent plot

Hi, Is there any way to make the dots that appear in a plot transparent? an example of what i would like to do is

plot(x,y, 'color', [1 0 0], 'alpha', 0.5)

Not with a line object, but you can use an old graphics 'trick' to get it done:

% Your data...
x = 1:10;
y = x.^2;

% Now make the 'line' (actually a surface)...
z = zeros(size(x));
S = surface([x;x],[y;y],[z;z],...
            'facecol','no',...
            'edgecol','interp',...
            'linew',2,...
            'edgealpha',.2,...
            'edgecolor','b');

Thanks for the information.

I did not specify that I am plotting 'dots'. But I also found this solution.

for i =1:len

p=patch([X(i) X(i) X(i)-width X(i)-width],[Y(i) Y(i)+height Y(i)+height Y(i)], color(s,:));

set(p,'FaceAlpha',0.125, 'EdgeColor', 'none');

end

This worked well for me Ian, thank you. However, I was hoping to plot the dots as circles rather than rectangles. Do you have a trick on how to do so?
