accuracy of numbers in stat. & fit boxes

Dear ROOTers,
I am preparing a publication and one of the comments of
a referee was that the numbers shown in the plots
(i.e. stat and fit boxes) showed too many digits.
Question : How can I specify the number of digits to be
displayed for the values in the stat and fit boxes ?

example :

Currently my fit info reads :

Chi2/ndf = 23.6736/ 33
p0 = 2.19976 +- 0.0606091

whereas I would like to have :

Chi2/ndf = 23.7/ 33
p0 = 2.200 +- 0.061

Something like

SetPrecision(par[0],3) // specify precision of 3 digits behind the .

would be a nice facility.
