it is not obvious, let's take an example :


plot2d(0,0,1,rect=[-1,-2,1,2],axesflag=0),xtring(0,0,"abcdefg")
a=gca()//current axes
t=a.children(1) // "abcdefg" Text handle

to keep relative coordinates you should use  a.data_bounds (the 
rect=...) to know the bounds of the figure and stringbox(t) to calculate 
the size of the box which contains the Text Handle t :

-->a.data_bounds
  ans  =

   - 1.  - 2.
     1.    2.

-->stringbox(t)
  ans  =

     0.    0.           0.1923497    0.1923497
     0.    0.1739130    0.1739130    0.
