Restrict number of digits in statistic box?

Hi,

I have a little question:
Is it possible to restrict the number of digits inside the statistic box? For example the fitparameter “Rate” (0.0002448±0.0000003) looks rather ugly (attachment). 2.448e-004 ± 3.e-007 would be nicer.

Thanks in advance!!
Chris

Perhaps TPaveStats::SetStatFormat would be helpful.
