Count/Sum Missing steps using a bar chart

[SkitzN27]

Hi guys,

This is the most complicated query I came across, can anyone please help?

Question:

Every candidate must follow this sequence of steps to get recruited by a company
1. Apply for Job
2. Pass the Exam
3. Interview
4. Sign the Offer Letter
5. Background Check

Some of the candidates don't reach the final step and may never get a job.
Some candidates reach the final step but might have some missing steps in between.
(Like Kyle got a job but he didn't go through the 'Pass the Exam' step so I'll count 1 missing step here.
Similary Jack never made it to the last step, he couldn't pass the exam, so we won't consider any missing steps for him.
For King, the last step was 'Sign the Offer Letter', but he has a missing step, he didn't go through
interview, so we will count that as 1)

So basically, for any of the candidates whatever be the last step, they shouldn't have any missing steps in between.

Now, I want to take the count of missing step and present it using a bar chart. Can anyone help please?
It's the most complicated query I came across so far.

Sample Data:

Load * inline
[
Date, CandidateName, CandidateStatus, Counter
1/1/2020 ,Dan, Apply for Job, 1
1/3/2020 ,Dan, Pass the Exam, 1
1/5/2020 ,Dan, Interview, 1
1/7/2020 ,Dan, Sign the Offer Letter, 1
1/9/2020 ,Dan, Background Check, 1
2/1/2020 ,Kyle, Apply for Job, 1
2/5/2020 ,Kyle, Interview, 1
2/7/2020 ,Kyle, Sign the Offer Letter, 1
2/8/2020 ,Kyle, Background Check, 1
1/9/2020 ,Jack, Apply for Job, 1
2/8/2020 ,King, Apply for Job, 1
2/9/2020 ,King, Pass the Exam, 1
2/11/2020 ,King, Sign the Offer Letter, 1
3/11/2020 ,Steve, Apply for Job, 1
4/11/2020 ,Steve, Interview, 1
5/11/2020 ,Ray, Apply for Job, 1
6/11/2020 ,Ray, Background Check, 1

since you are using aggregates, just count distinct applicants and that will be your baseline.

#Applicants - count of each step = missing for each step.

assuming a chart with Status as dimension

expression = count(distinct total CandidateName) - count(distinct Candidate)

[edwin]

another style is create a variable that stores the number of candidates and use that variable in the expression

with no change to your script.  this is the resulting straight table:
shows how many candidates missed a specific step

[edwin]

CandidateStatus	COUNT(distinct total CandidateName) - COUNT(distinct CandidateName)
Background Check	3
Interview	3
Pass the Exam	4
Sign the Offer Letter	3

I have to take a count of the missing steps, not candidates.

Whenever (for instance Interview/Pass the exam etc. is missing for a candidate, count it as 1)

[edwin]

so that means you count all the missing steps for one candidate as 1.  but is it one per step?  from your example if a candidate missed Interview and Pass the Exam and they are both counted as 1, how will you chart that?  shouldnt it be charted as follows?

interview  - 1
pass exam - 1

I'm not considering candidate anywhere.

It's just the sum of missing steps (no matter what the candidate was)
