First I would like to say that this is a great project for drawing graphs. I searched for graph drawing a lot of time.

I have problem with labels containing language specific characters such as  (Eacute in html syntax) and ? (Udoubleacute). They display space on the graph. Is there any way to display these characters?

I have an other problem but this is only a little question. How can I make an axis where there is no continuous measure, like this one (separated with comas): 1-5, 6-11, 12, 13, 14, 15, 16, 17, 18-24, Adult?

Best Regards,
