Creating some kind of Multislider with Jitter

I wanted to get a better visual representation for my Project. So I needed some kind of Multislider with a nice resolution, so can show the results of a logistic equation on a seperate window connected to a beamer. Therefore I started to work myself through the first Jitter tutorials.

#1 I scaled my floating point results to an integer range feeding it to a pak object connected to setcell and jit.matrix. But by comparing the multislider to the jit.pwindow. The results seem to be inverted. What have I got to change, to get the jit.pwindow moving in the same direction as the original multislider?
You will see what I mean if you use several parameter e.g.: 1.5 or 2.5

#2 In addition to that. Is there a way to use the pak-object so that I can send
in floating point numbers and get them displayed in jit.pwindow?

Any help is appreciated!
All the best
