As you know in QlikView, we have slider object which works great on the variable for what-if analysis. I have built the similar object using Sense APIs - "Sense-Variable-Slider"; which I have thoroughly tested on Chrome browser. It works on IE but yucks! Well, who wants to use IE!? If you decided to use IE, themes won't work.
sense-variable-slider supports following features:
Single Value Slider
Expression support for Start, End and Step values
Dual Value Slider with Min, Max and Step values
Custom Label with Expression Support
Custom Label Formatting
Note: For range slider/dual value slider – you will have two data points, min and max numbers are delimited by pipe" | ". So you should use SUBFIELD() function in QlikSense to extract the min and max values from the variable.
