Hello, I would like to show the legend for a1 and (a3,a4) together.

But when I run it both legend entry are displayed with a black filled dot and not with the red one (the second).

How can I fix it?

figure(1)
for i = z
    hold on; grid on; grid minor; axis equal;
    set(gcf, 'Color', 'White');
    set(gca, 'Fontsize', 12);
    set(gca, 'ZDir','reverse')
    a1 = scatter3(x*100,y*100,i*100,15,'filled', 'k');
    a2 = plot3(X3D*100, Y3D*100, Z3D*100, 'k');
    a3 = scatter3(C2(:,1),C2(:,2),C2(:,3),'filled', 'r'); %No Flow
    a4 = scatter3(C22(:,1),C22(:,2),C22(:,3),'filled', 'r'); %No Flow
    view(3)
    xlabel('x [mm]')
    ylabel('y [mm]')
    zlabel('z [mm]')
    legend([a1, a3 a4], 'Fiducial Markers', 'IPR Markers')
    title('Fiducial Markers vs. IPR Tracked Markers')
    subtitle('Wing NO Flow - 6DOF Fit')
end
