    Hi all, see enclosed. this is a straightforward (or not) attempt to plot a function. I am using lists, expression and a multi slider to show the values. I does not work. Meaning that the function visible is not the one that is meant to be seen. Interestingly if I use just a linear function all works... Any idea what is wrong? G.

      Lot's of ways to do this sorta thing. And a lot of details that can throw it off.
      Regarding your patch. zl group can only handle 256 list elements unless it is given an additional argument to specify more. ex. [zl 1000 group 1000]
      The other thing I would suggest is throwing a metro in there so the multi slider is continually refreshing. That way, you can tweak the $f2 input value until you find what you're looking for.
      I also added 'ghost lines' to the points (in the inspector) to give the waveforms more body.

      You can also use a line object to drive the drawing. Set the multislider in reverse point scroll mode to plot the function a single pass.

      Your range is set from 0 to 1… not -1 to 1. I think that's causing trouble too.
