The thread is 3 months old, but I thought I would comment…
I wrote an external called sa.function a while back that is like the function object and has multiple lines and bezier curve support. I attached a sample file with the curve you’re looking for. It has a lot of features and requires combinations of shift/alit/cmd/ctrl/right-click to manipulate the curves, so make sure to check out the help file.
The attachment only includes a OS X external, so let me know if you’re using Windows. It’s also only for Max5.
