Hi Kalen,
What you do should work. Could you send me a copy of your function?
When writing a TF1 referencing an interpreted or compiled function,
the function is tabulated at fNpx values in such a way that you can
always draw the function in the reading program even if the code
of the function is not available.
In your case, it looks like the function is being evaluated with a
division by 0.
