Hi,

I was trying to call chart.Posn. I ran into an unusual problem. It
complains that:

Error in strheight(axt):
   X11 font -adobe-helvetica-%s-%s-*-*-%d-*-*-*-*..., face 1 at size 11
could not be loaded.

I am wondering how to fix this? It seems something is missing from X11
device but I don't know what exactly to install. Thank you.

Robert
