Wow, thanks for pointing me to the master document, it's really impressive and very insightful! I incorporated the plugin you use (statFunctions), but now I hit the next road block: I cannot use it like this in a List (Radio) type question as an answer-option, since it tells me that I have too many arguments (11). I entered this:
statCountIf(G05Q01_SQ001_0, G05Q01_SQ001_1, G05Q01_SQ002_0, G05Q01_SQ002_1, G05Q01_SQ003_0, G05Q01_SQ003_1, G05Q01_SQ004_0, G05Q01_SQ004_1, G05Q01_SQ005_0, G05Q01_SQ005_1, "Ja") 
So I suppose I am not to use the function like this and I need to find a different approach.

I don't quite understand yet, how I am supposed to generate a number from the function, or where I have to put the code in order to make it work. I don't think the answer option is where I want to put the stat function (like I detailed above), but how else can I make it relevant for a statistical output?

@Carina, you are missing the ".sgqa" detail at your function. Also make sure "Ja" is the answer code assigned.
Check  www.limesurvey.org/manual/StatFunctions for more details.

@Joffm: Is there a page with link to all of your wonderful tutorials?

I incorporated the plugin you use (statFunctions),

For what you are trying to do, the plugin is totally useless. The plugin allows you to access answers from other respondents and present accumulated results over all respondents.

I only want to see results from one participant at the time, so I don't need the data to accumulate from different responses.

However, you only want to show the results for the current respondent.

so first of all, you will create equation type questions and make your calculations. Once you made your calculations and everything works, you can do the next step and show it in a graph.

From what I understood, this graph is not for you, but rather to show to the respondent within the survey, correct?

@Joffm: Is there a page with link to all of your wonderful tutorials?

No, you have to search in the German forum for them. Unfortunately Joffm didn't want me to create a sticky post including the links...

@holch
In the meantime I changed my mind.
So I'll create a new topic with only a short description and the links to the pdfs.

Btw:
The syntax of "sumifop" is wrong.
Either you use
sumifop("==","1",Q1,Q2,...).
You missed the operator.

Or
sumif("1",Q1,Q2,...)

Hi holch, thanks for responding!
The graph is not for the respondent and should not be accessible to them, it should be easily accessible in the background, preferably within the statistics section of Lime Survey so I don't have to export the data.... So I want Lime to calculate the ratio of Yes to No and n/a answers for each question group and then I want to access this calculation again and plot a pie chart displaying Yes vs. No.

The point is to see in the background how many of the certificates listed in the survey(each line in the matrix equals one certificate) are applicable to the respondent. I want to generate this for every question group and the end goal is to display a report sheet, which shows only the accumulated pie chart for each group as a quick overview.

Oh,
so you confused us.
In your first post you wrote

I am trying to generate a statistical output after every question group I have

But obviously you only want to calculate some values.
Then it is sufficient to create some (hidden) questions (e.g. of type list(radio)) and preset the values by your calculation equation.

Joffm

Looking back, it does sound like I want to do something different, so sorry for that!

I am still not understanding, how I can do what you propose? It sounds logical, but I don't know how to connect the two things. Do I need to assign the Yes-answers a variable to re-use it afterwards? Or how can I refer to it again afterwards, since I cannot display a Equation type question in the statistics. I am also not finding this connection between calculating and making it available in the stats in the manual - it' sso detailed, but I am somehow missing the connection..

You can't display results for single respondents in the statistics, this is not what it is for.

The statistics is always based on all respondents, not a single respondent.

So you will have to approach this differently I think.

Let's sum up your situation, if we get this right.
1. It is not a survey, but some kind of test / evaluation and the overall results for all respondents are not relevant to you. The single results of each respondent is what you are trying to get to. So this means the statistics are basically useless.
2. You have a number of question groups and for each question group you'll calculate some kind of result.

Exactly. The result I calculate for each question group is always the same - always an easy overview of how many of the answered questions are applicable to the singular respondent. It's like a qualification process and I can not have the data sets by multiple participants mixed up, correct.

But because you say the statistics are useless then: Can I not just filter for a specific aspect (I ask the name in the beginning), and then only display the answers that person gave? 

and then only display the answers that person gave

As you see in the filter options you only can filter the answer id. to identify a response.

But in my opinion this approach is not the best.
We always see this so called "statistics" as a quick overview during the data collecting.
The final analysis should be done in a different tool and also the creating of charts.
In this case you only need the calculated value (in your equation).
It is stored and exported.

Another way ist to use the notification email, where you may insert these values.
Or - more sophisticated - you use the plugin "pdfReport" and get this report in the notification mail.

Thank you so much for your help so far! I think I want to use pdfReport, but I am not certain how to create the according equation. I still want to display the summary of each group as a chart. Is this possible with the pdfReport?

If I only want to count the “Yes” answers, but I also need the value of the overall possible answers(e.g. 4 out of 10 answers in a give group are “Yes”) how can I creat a formula in the equation type question, which can plot a chart? I understand how I can sum up the given amount of the “Yes” answers, (sumif…) but how do I account for the second value and how do I have to incorporate it in the equation in order to have two values for my chart?

Have a lovely day,
Carina

You wrote in your first post

where the participants can answer "Yes", "No" and "n / a". 
...
I would do it like this: {sumifop("Yes",G05Q01_SQ001_0,G05Q01_SQ001_1,

This is the solution, except the wrong syntax of "sumifop"
But I can't believe that you coded the answer options "Yes", "No", "n/a".
So, what are the codes?

Here I take
1: Yes
2: No
9: DK

Knowing that you have two equations, maybe named "G05Yes" and "G05No"
1. {sumifop("==","1",that.G05Q01.NAOK,that.G05Q02.NAOK,that.G05Q03.NAOK,...)} all questions of the group
2. {sumifop("!=","1",that.G05Q01.NAOK,that.G05Q02.NAOK,that.G05Q03.NAOK,...)} all questions of the group

Now the chart.
After you made sure that it is possible to include such a chart into pdfReport - I do not know, you can either enter the equation directly (as I did in my tutorial) or just enter the resiult (G05Yes}, {G05No}

If it is not possible, so what?
You surely can insert a bar that shows the ratio - like the progress bar; it's only a filled rectangle and a not filled rectangle.

I still do not understand, why you want to have these charts created by LimeSurvey.
Isn't it sufficient to export the data - that include the variables "G05Yes", "G05No", and so on for all your groups.
Now you can add charts in Excel after each row (for each participant)
Here once created and then run a simple macro to repeat for all participants
 
And you can use these results to calculate a cluster analysis (just came to my mind)

But to be honest, I am tired to write English without reason and without seeing the design of your survey.
