MATLAB: Ovlay cdf plot on histogram

cdfgraphhistogramplot

Hi there,

I'm trying to overlay a cdf plot over a histogram like in this picture

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')

You are looking for the BarWidth property

plotyy(x1,y1,x2,y2,@(x,y)bar(x,y,1,'c', 'barwidth', 0.9),'stairs')

bin = 110:10:250;
binneddata = histc(data,bin) ./ length(data);
[y2,x2] = ecdf(data);
plotyy(bin, binneddata, x2, y2, @(x,y)bar(x,y,1,'c'), 'stairs')
