Try this:

x = linspace(-1, 3);
y = 2*((x >= 0) & (x < 1)) + 1*((x >= 1) & (x < 2));
figure
stairs(x, y)
grid
axis([-1  3    -1  3])

That looks like a waterfall plot.

In the future, you can scan through the list of plots in the Plots tab of the toolstrip for one whose thumbnail looks similar to the type of plot you want. This may help you identify a useful function. Even if it's not exactly what you're looking for, you may be able to adjust properties of that plot or use one of the plotting functions in the See Also section of that function's documentation page to get closer.

You cannot. Instead, ask for the outputs and plot the data yourself.

Example —

rng default  % for reproducibility
failuretime = random('birnbaumsaunders',0.3,1,100,1);T = 0.9;
cens = (failuretime>T);
[f,x,flo,fup] = ecdf(failuretime,'function','cumulative hazard',...
'censoring',cens,'bounds','on');
figure(1)
stairs(x, f, '-r')
hold on
stairs(x, flo, ':g', 'LineWidth',1)
stairs(x, fup, ':g', 'LineWidth',1)
hold off
xlabel('x')
ylabel('H(x)')
grid

Experiment to get the result you want.
