Hey,
I don't know how works Chart::Lines, but it seems to be based on GD. There's another module I use, also based on GD, called GD::Graph which can produce graphs with lines and text.

When I have to use this module and produce well formated text, I just have to use GD::Text, which allows me to choose the font, the size, etc... (note that there's also two sub-modules GD::Text::Align and GD::Text::Wrap to handle the alignment and the wraping (obviously)

You may want to play with these modules to see how the fit with Chart::Lines.

Hope this helps!
Briac
