How to draw cumulative histogram?

HI,

My bins = [ 10 10 20 40 50 60 70 80 80 80 90 90 90 100 100 100 100 100 ]

data = [ 4 8 14 35 49 55 66 74 76 78 82 84 90 92 94 96 98 100 ]

How can I draw cumulative probability histogram with these values?

Simplest would be something like this:

bins  = [  10 10   20  40 50 60 70 80 80  80  90 90 90 100 100  100 100 100 ];
data = [  4 8 14 35  49 55 66  74  76 78 82 84 90 92 94  96  98  100 ];
stairs(data,bins)
% or
bar(data,bins)

Hello,

You shoud do some tasks to approximate cumulative probability from your data. Then you just plot it. Below, will be a reference code

clear
My_bins  = [  10 10   20  40 50 60 70 80 80  80  90 90 90 100 100  100 100 100 ];
data = [  4 8 14 35  49 55 66  74  76 78 82 84 90 92 94  96  98  100 ];
bin = unique(My_bins);
[N,EDGES] = histcounts(data,bin);

ndist = N / sum(N);
cdist = cumsum(ndist);

plot(0.5*(bin(1:end-1)+bin(2:end)), cdist);
