This is case specific, but what you want to do is define the 8 interesting points, and then simply plot them. The text is less straightforward, but the following works.
gen={'S1' 'S2' 'S3' 'S4'};
X=[0 200 200 300 300 550 550 700];
Y=[2500 2500 2800 2800 3000 3000 3400 3400];
plot(X,Y);
hold on
ylim([2000 4000]);
xlabel('Something')
ylabel('Something else')
for i=1:numel(gen)
text((X(2*i-1)+(X(2*i)-X(2*i-1))/2),Y(2*i)-100,gen{i});
end

The cumsum and stairs functions should do what you want to arrange your data and create the plot. xlabel and ylabel will label the axes, and text can put the labels on the plot itself.
