OS: Linux
Status: UNCONFIRMED
Severity: normal

Hi!
I'm checking out Labplot2 2.5.0 (last sync and installation, 2018/04/16).
When you try to fit your data to a custom non-linear equation, like
Michaelis-Menten's [Vm*x/(Km+x)], and your spreedsheet contains the initial
(0,0) pair of data, you get this failure:
"Fit status: Iteration is no making progress towards solution".
When you remove (0,0), fitting proceeds.
