spanner angle

[Kate Sekula]

Is there a way to make a spanner angle upwards/downwards?  I am trying to 
create a textspanner line which starts at (0 . 0) and ends somewhere around (0 
. 2).  

Here's a minimal example:
     \once \override TextSpanner.style = #'line
     % \once \override TextSpanner...something about bound details on right?
     \times 2/3 {fis\startTextSpan gis fis!} a32 d, fis! 
     c^\accent\stopTextSpan
