If you are using the 'official' rrdtool then you will be using a
lucida sans typewriter font ... rrdtool at the moment can only work
with monospaced fonts ...

I have been thinking about using truetype fonts or rather let you
use truetype fonts, but have not yet found a sensible way to let
users configure this ... for example the whole alignement of
strings is very simple now due to the monospace fonts but will be
much more dificult with fonts of variable width ...

Also it is not clear to me how to sensibly allow font parameters to
be set ... for each string ...

so many questions ...
