I am doing something like

>> XX = 0; YY = 0;

>> h1 = plot( XX, YY, ['.y'] ); hold on

>> set(h1, 'markersize', 30);

>> h2 = plot( XX, YY, ['.r'] );

This gives a very nice red dot on yellow background that I want to use as a special symbol, but is there a way to make these red on yellow dots appear as such in the legend box? Can you 'merge' handles, I know you can do >> legend([h1,h2],'foo','foo2'); but that gives two legend entries where I want the red/yellow dot treated as a combine unit as you see them in the plot.

It might be easier to just play around with marker size/line width combos to get the same effect without duplicating the plotted data:

h = plot(0,0, ...
         'marker', 'o', ...
         'markerfacecolor', 'r', ...
         'markeredgecolor', 'y', ...
         'linewidth', 2);
legend(h);
