Why I'm not able to redraw a line?

This is the situation I have:

I'd like to redraw the line (i.e. its height) every time I tweak the knob.
I can see the value change using "watch", but the line is not redraft. Where am I wrong?
Hope you can help me.
Thanks for your time, as usual!

All inputs you name are automatically converted to an instance variable. So your input "height" is also available as @height. But you also declare another variable as @height. Rename one of them.
