titleformat+tickmarks

I have 2 queestions:

1- concerned about the title font format:

fot the title

tit:=sprintf("W=%g,D=%g,f=%g,M=%g,N=%g,q=%a",Omega,Delta,phi,M,N,q);
                        "W=0.2,D=0,f=0,M=0,N=0,q=-10"

the little problem in the last value q=-10 it appear theta=10 even the sign (-) invisible

2- the sign(-) at the tickmars on y axis appear at the right which is should be at the left.

any helful sugestion .
