[Xymon] graphs customising

Hi all,

I have been trying to modify the default look of the graphs generated by xymon without any success. I have tried to play with hobbitgraphs.cfg, changed few things but it sill does not want to generate better looking graphs.

I have seen many nice graphs generated by RRD but can't make it work with xymon.

Do anyone knows about any decent tutorial somewhere online?

Many thanks.

Oliver
