Re: Bell curve

Hi all,

After trying i got a graph like below.

histogram.png

I am not sure is this correct.

I am using same expression for both bar and line.

Dimensions: class([`total_time_taken`],'00:05:00.000','Timetaken')

Measures:

Bar Graph: count({$<subject_id={'2'},subject_status={'passed','completed'}>}user_id)

Line : count({$<subject_id={'2'},subject_status={'passed','completed'}>}user_id)

I am not getting how to use the NORMDIST() for line.

I used Measure for line as below,This is not working.

Only(Normdist(class(user_id,0),Avg(total user_id),Stdev(total user_id), 0))*0*Count(total user_id)

Please anyone explain about the Normdist() syntax regarding this example. in original post i have added sample data and .qvf file.

Thanks,

Pramod

Hi Pramod,

This a link to an excellent article written for QlikView illustrating how to solve the same problem as you have outlined.  The example will also work in Qlik Sense.  Recipe for a Histogram

Hope this helps.
