Hi there,
I'm trying to overlay a cdf plot over a histogram like in this picture
https://dl.dropbox.com/u/54057365/All/hist.JPG
I'm using this code but the cdf plot is not showing up over the histogram.
hist(x)
hold on
cdfplot(x)
I would appreciate any help.
Thanks

It's there but it's on the histogram scale and it is obscured by the bars. Try this instead to put the cdf on a separate y axis:
x = randn(30,1);
[y2,x2] = ecdf(x);
[y1,x1] = hist(x);
plotyy(x1,y1,x2,y2,@(x,y)bar(x,y,1,'c'),'stairs')
