Re: [ferret_users] cumulative distribution curve

Dear Ryan

thank you for the reply, but I think I will explain the problem little more specifically

here i am having 36 points in my x-axis (attached as hval)
and I have tried to find out the frequency per year (1900-2100 which means 201yrs) by running the below command. But I am getting values for the years which don't have any occurrence just the same as the previous year frequency (attachment frequency.txt).  I want those years with zero frequency as the number zero only not the value from previous year.  
code:
DEFINE AXIS/X occurences = hval[x=1:33]
LET pdf = I[gx=occurences]
DEFINE AXIS/X=1900:2100:1 my_intervals
let frequency=pdf[gx=my_intervals@sum]

thanks
gopika
