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.
