Usually when I want to plot two sets of data on a single graph, I use plot (x1, y1, x2, y2) or the plot, hold on, plot, hold off method. This works great. I recently began using lots of weibull fits and even with these wblplot, hold on, wblplot, hold off worked just as well. The problem I am having comes when I begin to censor data for Weibull fits. 

I can use probplot('weibull', Y, cens, freq) to do censoring very well and I can do this many times but I now have a set of data that has three different zones where I would like to plot the one set of data and the 3 weibull fits for the three zones. I tried probplot('weibull', Y, cens1 cens2 cens3) but of course this won't work but when I use probplot, hold on, probplot, hold off, it only keeps the last probplot I did and won't combine them.

Is there any way to plot multiple Weibull fits for the same set of data or even just do the probplot 3 times and combine the graphs? 

Still haven't found a good way besides really sketchy photoshopping... is there just no way?

Why would you use

hold off

if you're still wanting to add further onto the same plot?

I don't have probplot() to look at, just saying...

'Hold on' may not work with probplot function. But you can use matrix for m=
ultiple plots. Let's say x1 is first set of data and x2 is second set of da=
ta,=20
probplot('weibull',[x1 x2])
Note that x1 and x2 have same number of samples. Example is appeared in the=
