x1 = rand(1,5);
y1 = rand(1,5);
x2 = rand(1,7);
y2 = rand(1,7);

plot(x1, y1, 'or', 'MarkerSize',20)
hold on
plot(x2, y2, 'sg', 'MarkerSize',20)
hold off
set(gca, 'Color','none', 'GridAlpha',0, 'XColor','none', 'YColor','none', 'ZColor','none') % This Turns Off Everything That Would Make It Appear As A ‘plot’
producing (in these random calls):
