Hi there,

and welcome to the PyX club :)

The current version of PyX is 0.15 for the Fedora rpm, by the way.
Independent of that:

Presumably, your ts is not a list of numbers but strings (labels). You
probably want to convert them or use them as labels by using
`xname=ts` instead of `x=ts`.

Cheers
Michael
