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...

Hi all,

Any idea what is wrong?

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.

Thanks a lot for the examples.

All good now.

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