probplot and hold on

How can I plot more than two "probplot" in one graph? I used "hold on" but it doesn't work. It only shows the last graph. And also please help me about using probplot in for loop, to draw in one graph.

x1 = wblrnd(3,3,100,1);
x2 = raylrnd(3,100,1);
x3 = raylrnd(3,100,1);
probplot('weibull',[x1 x2 x3])

Thanks. What if x dataset is very large? For example more than 100. How can I use for loop?

[Azzi Abdelmalek]

y=[] 
for k=1:5
x=wblrnd(3,3,100,1);
y=[y x]
end
probplot(y)

It is also possible to do

h = probplot(gca,x2)

to add x2 to an existing probability plot. This has the advantage that the x vectors don't need to have the same length. The disadvantage is that you'll want to change the color using h, to be different from the color of the stuff already on the plot.

[Azzi Abdelmalek]

Exact, you can also set different color

h=probplot(gca,x2);
set(h,'color','g')
