You want just to change your labelling?
No problemo, Baby.

xmin,xmax = ........
ymin,ymax = ........
...
tbl=...

ic=contourf(tbl,
             extent=(xmin,xmax,ymin,ymax))
axis([xmin,xmax,ymin,ymax])

show()

Bon courage.

Now, if you want to change your *values*, as Alexa understood, then be 
more precise, please.
