--- Comment #2 from Stefan Gerlach <stefan.gerl...@uni-konstanz.de> ---
It looks like you did an unweighted fit. In this case the calculated chi^2 is
correct. To do a weighted fit, you have to select "Instrumental" for y-Weight
and the error column in the dock widget.
There were two related bugs that are fixed now:
1. Weighted fitting was possible only for data from spreadsheet (not from a
curve)
2. weighted fitting failed when the given error was zero

I will release a Windows package for 2.7.0rc3 tomorrow on
https://theorie.physik.uni-konstanz.de/gerlach/labplot/.
Let me know if that works for you.
