x = [0 : 0.1 : 12] * pi;
y = sin(x);
z = cos(3 * x);
figure();
plot3(x,y,z, '--d','color','b','markerfacecolor','y','markersize',4);

#Change color as per requirements

@Ye Try playing with markers..Like this

plot3(x,y,z,'-s','MarkerSize',10,...
    'MarkerEdgeColor',[1 .6 .6],...
    'MarkerFaceColor','g')

More customization options can be explored here.
