MATLAB: How do you get a legend to have different marker sizes

figurelegendmarker sizeMATLABscatterscatterplotsize;

I have a set of dummy points and I am trying to make a legend with most of the markers being the same size but 3 of them being different sizes(can be based on the size of the points in the scatter plot or resized individually) list1-5 should have the same marker size and Phase A should have a larger marker size Phase B should have the normal marker size and Phase C should have a small marker size. The text should remain the same in all cases.
figure
    hold on
    %sets up data for the legend
    list1 = scatter(NaN,NaN, 40, 'r', 'filled');
    list1.MarkerEdgeColor = 'k';
    list2 = scatter(NaN,NaN, 40, 'y', 'filled');
    list2.MarkerEdgeColor = 'k';
    list3 = scatter(NaN,NaN, 40, 'g', 'filled');
    list3.MarkerEdgeColor = 'k';
    list4 = scatter(NaN,NaN, 40, 'c', 'filled');
    list4.MarkerEdgeColor = 'k';
    list5 = scatter(NaN,NaN, 40, 'm', 'filled');
    list5.MarkerEdgeColor = 'k';
    list6 = scatter(NaN,NaN, 90, 'w', 'filled');
    list6.MarkerEdgeColor = 'k';
    list7 = scatter(NaN,NaN, 40, 'w', 'filled');
    list7.MarkerEdgeColor = 'k';
    list8 = scatter(NaN,NaN, 10, 'w', 'filled');
    list8.MarkerEdgeColor = 'k';
  lgd = legend([list1 list2 list3 list4 list5 list6 list7 list8], 'list1',...
   'list2', 'list3', 'list4', 'list5', 'Phase A',...
   'Phase B', 'Phase C','AutoUpdate ','Off', 'Location', 'northwest');

Since those are all dummy scatter() calls to create the legend entries, replace them with calls to plot(), such as
list1 = plot(nan, nan, 'MarkerSize', 40, 'MarkerEdgeColor', 'k', 'MarkerFaceColor', 'r');
