The numbers over the bars respect the Field format. It doesn´t match the axis format.
The axis format is configurated in Properties>Numbers.

First of all, thanks.
What you suggest seems to be the easy solution.
But I'm trying to understand why in QV8.5 both axis and bars values where affected by thousands symbol in the expression number settings, and now only the axis is affected.
Have i missed something or something is changes in QV?
