Plotting - Control Legend

Hi,

I have data coming in and I am plotting it.

Is there a way to preassign a legend so that the marker face colour is assigned to the condition it represents.

For instance, I would like the graph to be like the picture attached, but the legend to be there at the beginning of the plot and for the descriptions "Item X" to be fixed to the specified marker i.e.

Yellow = Item A
Magenta = Item D

etc

An example codeblock to test is provided below. It is based on what I have.

clf
MarkerFaceColor{1} = [1 1 0];                % YELLOW MarkerFaceColor  is item A
MarkerFaceColor{2} = [1 1 1];                % White MarkerFaceColor   is item B  
MarkerFaceColor{3} = [0 1 0];                % Green MarkerFaceColor   is item C
MarkerFaceColor{4} = [1 0 1];                % Magenta MarkerFaceColor is item D
Black = [0,0,0];
x = 1:1:10;
y = repelem(1,10);
Color = [1 3 4 2 2 3 1 4 3 3];
legend() %? MarkerFaceColor - Item X
for i = 1:1:10
    pause(1)
    plot(x(i),y(i),"Marker","o","MarkerEdgeColor",Black,"MarkerFaceColor",MarkerFaceColor{Color(i)},"MarkerSize",17)
    legend()%? MarkerFaceColor - Item X
    ylim([0 2])
    hold on
      
end
