txt1=[{'A100'};{'B100'};{'C100'};{'X1'};{'X2'}];
y=[100;150;200;135;140];
x=[200;250;300;225;235];
figure(1),scatter(y, x, 'b^');grid off;
text(y, x, txt1);
title('points')
xlabel('Y');
ylabel('X');
line(y,x,'Color','k','LineWidth',1);
%I need to make X1 and X2 red in the figure1 while the other points are black.

% size|color in rgb | marker
figure(1),scatter(y, x, 36, [zeros(numel(y)-2,3);1 0 0;1 0 0], '^');grid off;
text(y, x, txt1);
title('points')
xlabel('Y');
ylabel('X');
line(y,x,'Color','k','LineWidth',1);
