Dear Forum,

I struggle both conceptually and technically to implement a so called Lambda Slider in LimeSurvey. 

Such a slider triggers two different functions, which determine the size of two bars. You can find a working version under the following link:
experiments.evullab.org/lambda-slider  

The developer of this slider also has an informative github page, which has code to embed a standalone slider in Qualtrics, see here: GitHub - jameswhqi/wtr-slider-data: Data and code for the Lambda Slider paper Embedding the standalone slider also works in Limesurvey. I just made a text display question, which contains a script for the iframe, see here

prif.limequery.com/776966?lang=en  

However, I struggle to record the values of the slider in my responses so I could use and analyse them. Do you know how I could do this in limesurvey?

Also I would be interested in how you would approach building the Lambda slider from the scratch in Limesurvey, so I would not have to rely on the external website and the iframe solution.

Thanks for help!
Best,
Felix


 

Hi,
in my opinion you can use @tpartners "range slider" script.
Adapt to two sections
Change the display from text field to progressbar. (if you want)
And enter the correct algorithm to calculate the values

Thanks a lot!

I will look into this.
