MATLAB two Graph Plotting

x = 1:100;

y = ones(1,100);

y1 = ones(1,100);

y2 = ones(1,100);

y3 = ones(1,100);

y = x;

y1 = x+2;

y2 = x+50;

y3 = x+100;

plot(x,y2,x,y3);

figure(1);

xlabel("x");

ylabel("y");

legend('y2,y3');

plot(x,y,x,y1);

figure(2);

xlabel("x");

ylabel("y");

legend1('y,y1');

When I am running figure(2) is coming blank. Why is it so?

%if true
  % code
% end
figure(1)
plot()
...
...
figure(2)
plot()
...
...

Follow this sequence for plotting. There is no legend1. Only legend
