MATLAB: Transparent plot

Question

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)

Answer 1

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');
